Our SPD Surge Protective Devices are the quintessential defenders in the realm of electrical safety, meticulously crafted to safeguard your invaluable electronics from the unpredictable wrath of voltage surges. Large single surge events, such as the formidable lightning strike, can unleash hundreds of thousands of volts, potentially wreaking havoc on equipment. Yet, remarkably, lightning and utility power anomalies account for only 20% of transient surges. The silent majority, a staggering 80%, actually originate from within. While these internal surges may not possess the dramatic force of a lightning bolt, their frequency and persistence subtly corrode the delicate electronic components in your facility over time.
A power surge represents a brief but intense overload of voltage that poses a significant threat to electrical devices, often resulting in their premature failure. The devastation caused by these surges extends across a wide array of household essentials, affecting and drastically shortening the lifespan of:
NEW 2020 National Electrical Code Requirements
In accordance with the pioneering 2020 National Electrical Code, it is now mandated that all new and renovated homes be fortified with Listed and Approved Type 1 or Type 2 Surge Protective Devices, establishing a new benchmark in safety standards.
Type 1:
A permanently connected Surge Protective Device, serving as a stalwart barrier against both external and internal surges. It offers flexible installation options for either the interior or exterior of your home.
Type 2:
This robust, permanently connected Surge Protective Device is strategically positioned within or adjacent to the breaker box, engineered to combat both internal and external surges.
Type 3:
Enhanced protection with a point-of-use Surge Protective Device, offering an additional layer of security when combined with Type 1 or Type 2 SPDs, ensuring full compliance with the 2020 code requirements.
For unmatched protection, utilize a strategic combination of Type 1, 2, and 3 SPDs to thoroughly fortify your home against any electrical anomaly.

Selection of SPD:
When selecting a Surge Protection Device (SPD) for your power distribution system, it's essential to carefully evaluate certain key characteristics that define an effective lightning protection system. This ensures that the electrical installation within a building is optimally safeguarded, providing peace of mind and enhanced security.
Additional essential characteristics for selecting an SPD are typically predefined and tailored for a specific electrical installation, providing bespoke protective solutions tailored to your needs.
This sub-sectionDesign of the Electrical Installation Protection SystemThis section offers an in-depth analysis of the criteria essential for selecting an effective protection system. It considers the specific installation characteristics, the sensitive equipment that requires safeguarding, and the overall environmental context for a comprehensive protection strategy.
Location and Types of SPD:
Connection of SPD:
Ensure that SPD connections to loads are kept as brief as possible to effectively minimize the voltage protection level (installed Up) at the terminals of the equipment being shielded, optimizing protection and functionality.
The overall length of SPD connections to both the network and the earth terminal block should be meticulously kept under 50 cm to ensure maximum efficiency and protection.
SPD Enclosures: Options include SPD housed in a plastic enclosure or SPD housed in a metal enclosure, providing flexibility in installation and design preferences.
