Best Intermatic Surge Protectors: A Comprehensive Buying Guide
Surge protection is a critical, yet often overlooked, aspect of safeguarding valuable electrical equipment and ensuring the longevity of home and commercial systems. Electrical surges, transient voltage events, can originate from both external sources – like lightning strikes – and internal sources – such as the cycling of high-power appliances. These surges, even seemingly minor ones, accumulate over time, degrading components and ultimately leading to premature failure. Intermatic, a well-established name in electrical controls, offers a diverse range of surge protectors designed to mitigate these risks. This guide provides a detailed analysis of key factors to consider when selecting the best Intermatic surge protectors for specific needs, moving beyond simple specifications to focus on practical application and long-term value. The selection process requires careful consideration of the environment, the equipment being protected, and the level of protection desired. A poorly chosen surge protector offers a false sense of security, while the right one can provide years of reliable defense against damaging voltage spikes.
1. Surge Protection Level (Joules Rating)
The joules rating is arguably the most important specification when evaluating surge protectors. It represents the amount of energy a device can absorb before failing. A higher joules rating indicates a greater capacity to handle larger surges and a longer lifespan, as the protector will degrade more slowly with each surge event. For basic electronics like lamps and phone chargers, a lower joules rating (300-600 joules) might suffice. However, for sensitive and expensive equipment like televisions, computers, and home theater systems, a rating of 1000 joules or higher is highly recommended. Intermatic offers models ranging from 360 joules to over 2000 joules, catering to diverse protection needs.
Data from the IEEE (Institute of Electrical and Electronics Engineers) suggests that the average household experiences approximately 20 surges per month exceeding 100 volts, and several more that are smaller but still contribute to cumulative damage. A surge protector with a lower joules rating will likely be exhausted after absorbing only a handful of significant surges, rendering it ineffective. Furthermore, Intermatic’s whole-house surge protectors, typically boasting higher joules ratings (often exceeding 1800 joules), are designed to handle the larger surges that enter the electrical system from external sources, protecting all connected devices, not just those plugged directly into the protector. Choosing a protector with a joules rating appropriate for the anticipated surge environment is therefore paramount.
2. Response Time
Response time, measured in nanoseconds, refers to how quickly a surge protector can react to a voltage spike and begin diverting excess energy. A faster response time is crucial, as even a brief exposure to a surge can damage sensitive electronics. Ideally, a surge protector should clamp the voltage within acceptable limits in less than one nanosecond. While most surge protectors claim response times within this range, the actual performance can vary. Intermatic consistently publishes detailed specifications for its products, allowing for informed comparisons.
Independent testing conducted by Consumer Reports consistently demonstrates that response times can differ significantly between models, even those with similar joules ratings. A slower response time allows more energy to pass through to the connected equipment, increasing the risk of damage. Intermatic’s higher-end models often incorporate more sophisticated circuitry designed to minimize response time, utilizing technologies like silicon avalanche diodes (SADs) and metal oxide varistors (MOVs) optimized for speed. Furthermore, the length of the power cord can also subtly impact response time; shorter cords generally result in faster clamping.
3. Number of Outlets & Outlet Configuration
The number and configuration of outlets are practical considerations directly impacting usability. Consider the number of devices needing protection and their plug types. Intermatic offers surge protectors with varying outlet counts, from basic two-outlet models to power strips with eight or more outlets. Outlet configuration – the arrangement of outlets and the presence of features like rotating outlets or USB charging ports – is also important. Rotating outlets accommodate larger power adapters, while USB ports provide convenient charging for mobile devices.
A common mistake is underestimating the number of outlets required. Home entertainment centers, computer workstations, and home offices often require multiple outlets for various components. Intermatic’s power strips with strategically spaced outlets are designed to prevent “plug crowding,” ensuring all devices can be connected without blocking adjacent outlets. Data from the US Energy Information Administration (EIA) indicates a growing number of electronic devices per household, further emphasizing the need for surge protectors with sufficient outlet capacity. Consider future needs as well; it’s often better to choose a protector with a few extra outlets than to be constantly swapping devices.
4. Protection Modes & Features
Surge protectors employ different protection modes to safeguard against various types of surges. The most common modes include Line-to-Neutral (L-N), Line-to-Ground (L-G), and Neutral-to-Ground (N-G). Comprehensive protection requires all three modes. Intermatic’s best intermatic surge protectors typically offer all three modes, providing a more robust defense against a wider range of surge events. Additional features, such as indicator lights (indicating protection status) and circuit breakers (providing overload protection), enhance safety and usability.
Research from UL (Underwriters Laboratories) highlights the importance of multi-mode protection. Surges don’t always follow a predictable path; they can travel through different wiring configurations. A surge protector that only protects against L-N surges, for example, will be ineffective against surges traveling through the ground wire. Intermatic’s whole-house surge protectors often incorporate cascading protection, where multiple stages of surge suppression work together to further reduce the voltage reaching sensitive equipment. The inclusion of a thermal fuse or circuit breaker is also a critical safety feature, preventing overheating and potential fire hazards.
5. Mounting Options & Form Factor
The physical form factor and mounting options influence where and how a surge protector can be used. Intermatic offers a range of options, including standard power strips, wall-mount models, and whole-house surge protectors designed for installation in electrical panels. Wall-mount models are ideal for saving space, while whole-house protectors provide comprehensive protection for the entire electrical system.

FAQs
What is the difference between a Type 1, Type 2, and Type 3 surge protector, and which Intermatic model fits each category?
Type 1 surge protectors, also known as whole-home protectors, are installed at the electrical service entrance and are designed to divert large voltage surges caused by direct lightning strikes or utility switching. They have a high surge current capacity, typically 60kA or higher. Intermatic’s SP8260 is a prime example of a Type 1 protector, offering robust protection for the entire electrical system. These are the first line of defense.
Type 2 protectors, like the Intermatic SP8240, are installed at subpanels or critical equipment and protect against smaller, more frequent surges that get past Type 1. They typically handle surges up to 20kA. Type 3, or point-of-use protectors (like power strips with surge protection), are the final layer, protecting individual devices. Intermatic doesn’t directly offer dedicated Type 3 protectors, but their Type 1 & 2 models effectively reduce the surges reaching those devices, maximizing their lifespan. Understanding this tiered approach is crucial for comprehensive surge protection.
How do I determine the correct surge current capacity (kA) I need for my Intermatic surge protector?
Determining the appropriate kA rating depends on your risk level and the value of the equipment you’re protecting. Areas prone to frequent lightning strikes or with unreliable power grids require higher kA ratings. A general rule of thumb is to assess the potential surge energy and the sensitivity of your electronics. For basic appliance protection, a 6kA to 10kA protector might suffice.
However, for sensitive electronics like computers, home theater systems, or smart home devices, a higher rating (20kA or more) is recommended. Intermatic’s SP8260, with its 60kA capacity, is ideal for comprehensive protection in high-risk areas. Consider also the LET-THRU voltage rating; a lower LET-THRU indicates better protection, as it allows less voltage to pass through during a surge. Data from the IEEE suggests that even a small reduction in LET-THRU can significantly extend the lifespan of sensitive electronics.
What is LET-THRU voltage, and why is it important when choosing an Intermatic surge protector?
LET-THRU voltage represents the maximum voltage that passes through the surge protector during a surge event. A lower LET-THRU voltage indicates a more effective protector, as it clamps down on the surge more efficiently, minimizing the voltage reaching your connected devices. It’s measured in volts and is a critical specification often overlooked.
While a high surge current capacity (kA) is important, a high LET-THRU voltage can negate its benefits. For example, a protector with a 60kA rating but a 400V LET-THRU might not adequately protect sensitive electronics. Intermatic’s SP8240 and SP8260 models typically have LET-THRU voltages under 330V, providing a good balance between surge current capacity and voltage clamping. Look for protectors with a LET-THRU of 330V or lower for optimal protection.
How does an Intermatic surge protector differ from a standard power strip?
Standard power strips primarily provide additional outlets and may include a basic level of surge protection, often around 600 Joules. However, this protection is typically insufficient for handling significant surges. Intermatic surge protectors are engineered specifically for surge suppression, utilizing technologies like silicon avalanche diodes (SADs) or metal oxide varistors (MOVs) to divert surge energy away from connected equipment.
Intermatic protectors offer significantly higher Joule ratings (energy absorption capacity) and faster response times than standard power strips. The SP8260, for instance, boasts a Joule rating of over 72,000 Joules, far exceeding the capacity of most power strips. Furthermore, Intermatic models often include status indicators to alert you when the protector has reached the end of its lifespan and needs replacement, a feature rarely found in standard power strips.
What is the lifespan of an Intermatic surge protector, and how do I know when it needs to be replaced?
The lifespan of a surge protector is determined by the number and magnitude of surges it absorbs. Over time, the internal components degrade, reducing its effectiveness. Intermatic surge protectors are designed to provide years of reliable protection, but they are not indefinite. The Joule rating indicates the total energy the protector can absorb over its lifespan.
Most Intermatic models feature a status indicator light. If this light turns off or changes color (as indicated in the product manual), it signifies that the protector has reached the end of its lifespan and needs to be replaced. Even without a status indicator, it’s recommended to replace surge protectors every 2-3 years, or immediately after a significant surge event, like a nearby lightning strike. Regular inspection and timely replacement are crucial for maintaining optimal protection.
Can I daisy-chain Intermatic surge protectors to increase protection?
Daisy-chaining surge protectors (plugging one into another) is generally not recommended and can actually decrease overall protection. This is because it introduces additional impedance and can create a bottleneck, hindering the surge protector’s ability to effectively divert energy. The combined protection won’t be the sum of the individual protectors; it will likely be less.
Instead of daisy-chaining, it’s far more effective to implement a layered approach to surge protection. Start with a Type 1 whole-home protector (like the Intermatic SP8260) at the service entrance, followed by Type 2 protectors at subpanels or for critical equipment (like the SP8240). This provides comprehensive protection without compromising the effectiveness of each device. IEEE standards emphasize the importance of avoiding cascading surge protection.
What safety certifications should I look for when purchasing an Intermatic surge protector?
When selecting an Intermatic surge protector, prioritize models with recognized safety certifications. UL (Underwriters Laboratories) listing is paramount, indicating that the product has been tested and meets stringent safety standards. Look for the UL 1449 standard, specifically for surge protection devices. This certification verifies the protector’s ability to safely suppress surges and prevent fire hazards.
