Our SPD Surge Protective Devices are meticulously engineered to shield your precious equipment from unexpected transient surge conditions. When monumental single events, such as lightning strikes, unleash hundreds of thousands of volts, they can trigger immediate or occasional equipment failure. Interestingly, lightning and utility power anomalies contribute to just 20% of transient surges. The powerhouse behind the remaining 80% is internal surge activity, which, despite being lower in magnitude, occurs with greater frequency. Continuous exposure can silently degrade the sensitive electronic equipment nestled within your facility, compromising its longevity and performance.
Experience the peace of mind that comes with knowing your electrical systems are safeguarded against power surges, those fleeting overvoltage events notorious for damaging electrical devices. These surges are a prevalent culprit for the untimely failure of:
NEW 2020 National Electrical Code Requirements
In the pursuit of ultimate safety, all new and renovated homes must now embrace the protection offered by Listed and Approved Type 1 or Type 2 Surge Protective Devices. This standard ensures your home is fortified against unpredictable power surges.
Type 1:
This is a permanently connected Surge Protective Device, designed to guard your home against both external and internal surges. Its versatile installation allows it to be positioned either inside or outside the home, providing robust security.
Type 2:
A permanently connected Surge Protective Device that nests in or next to the breaker box. It stands as a vigilant protector against both internal and external surges alike.
Type 3:
Offering an extra layer of protection, this point-of-use Surge Protective Device must pair with Type 1 or Type 2 SPDs to satisfy the 2020 code requirements, ensuring an impenetrable defense strategy.
Achieve the pinnacle of protection by utilizing a combination of Type 1, 2, and 3 SPDs. This trio ensures comprehensive safety and peace of mind for your electrical systems.

Optimal SPD Selection:
When it comes to a power distribution system, the critical features to consider for selecting a high-performing SPD to safeguard your building's electrical setup include:
Additional Essential Characteristics for SPD Selection are Predefined for your Electrical System.
This Sub-Section Details Designing a Comprehensive Electrical Installation Protection System This section elaborates on the detailed criteria for selecting the optimal protection system according to the specific characteristics of your installation, the equipment needing protection, and the surrounding environment.
Strategic Location and SPD Types:
Efficient Connection of SPD:
Ensure SPD connections to the load are minimized to effectively reduce the installed voltage protection level (Up) on the terminals of your safeguarded equipment.
The cumulative length of SPD connections to both the network and the earth terminal block should remain within 50 cm.
