Our SPD Surge Protective Devices are engineered to stand as a robust shield against unpredictable transient surge conditions. These surges, which can reach staggering voltages especially during massive events like lightning strikes, pose a significant threat by causing immediate or latent equipment failures. While such events are dramatic, they account for only 20% of all transient surges, with the remaining 80% being generated internally within facilities. Although often less potent individually, these frequent internal surges can perpetually erode the integrity of sensitive electronic devices, leading to premature degradation. Protect your investments with our industry-leading solutions that ensure safety and longevity for your equipment.
A power surge is a sudden spike in voltage that can wreak havoc on your electrical devices and is a prevalent culprit behind electrical equipment failures. These surges can result in damage and significantly diminish the lifespan of:
NEW 2020 National Electrical Code Requirements
Innovative and fortified protection measures are now mandated for all newly built and renovated homes. These abodes must be equipped with Listed and Approved Type 1 or Type 2 Surge Protective Devices, ensuring a solid defense against potential surge threats.
Type 1:
This is a robust, permanently connected Surge Protective Device offering comprehensive protection against both external and internal surges. Versatile in installation, it can be situated either inside or outside the home, providing a flexible solution for surge protection.
Type 2:
Designed as a permanently connected Surge Protective Device, this unit is strategically installed in or adjacent to the breaker box. It offers steadfast protection against both internal and external surges, acting as a reliable line of defense for your electrical system.
Type 3:
For an additional layer of safety, this point-of-use Surge Protective Device offers extra protection. It is essential to use it in tandem with Type 1 or Type 2 SPDs to fully comply with the stringent 2020 code requirements, ensuring the highest standards of electrical safety.
Achieve unparalleled protection by utilizing a combination of Type 1, 2, and 3 SPDs, collectively forming the most comprehensive defense strategy against power surges.

Selection of SPD: Ensuring Optimal Protection
For a robust power distribution system, the key characteristics that guide the definition of the lightning protection system and the selection of an appropriate SPD for safeguarding an electrical installation within a building include:
The specific characteristics for selecting an SPD are predefined to ensure compatibility and efficiency within an electrical installation.
This Sub-section: Delving Deeper Into Protection Design Design of the Electrical Installation Protection System: Crafting a Fortress of Safety This section provides detailed guidelines for selecting the protection system based on the installation's characteristics, the equipment requiring protection, and the environmental context.
Connection of SPD: Precision and Protection
For optimal efficiency, ensure SPD connections to loads are minimized in length to reduce installed Up voltage protection levels at the terminals of protected equipment.
SPD Connection Length: The total connection length to the network and earth terminal block must not exceed 50 cm for maximum effectiveness.
SPD Enclosure Options: Choose Between Plastic and Metal
