Surge Protective Devices (SPDs) are engineered to shield your valuable electronics from transient surge conditions. These devices are vital in defending against large single surge events, including lightning strikes, which can unleash hundreds of thousands of volts, potentially causing immediate or gradual equipment malfunction. Interestingly, lightning and utility power irregularities only account for 20% of transient surges. The other 80% of surge activity stems from internal sources. Although these surges tend to be less intense, they occur far more often, leading to continuous exposure that can severely degrade the performance and lifespan of sensitive electronic equipment within your facility.
Products features
1. Robust 1P+N phase protection designed for both AC and DC systems, ensuring comprehensive safety.
2. Features a convenient pluggable module to streamline installation and maintenance processes.
3. Offers a high discharge capacity with rapid response times to efficiently counteract surge threats.
4. Equipped with dual thermal disconnection devices, enhancing protection reliability against surges.
5. An intuitive green window indicator shifts color to signal faults, coupled with a remote alarm control for immediate alerts.
A power surge is a transient spike in voltage that can damage electrical devices, often leading to equipment failure. Surges can inflict harm and shorten the lifespan of:
The National Electrical Manufacturers Association highlights that the average home contains approximately $15,000 worth of equipment susceptible to damage from power surges.
Common Causes of Surge:
An estimated 80% of surges are attributed to internal sources.
Internal Sources:
External Sources:
NEW 2020 National Electrical Code Requirements
All new and renovated homes must comply with the 2020 National Electrical Code by being equipped with Listed and Approved Type 1 or Type 2 Surge Protective Devices.
Type 1:
A permanently connected Surge Protective Device designed to guard against both external and internal surges. It offers flexible installation options, either inside or outside the home.
Type 2:
A permanently connected Surge Protective Device installed at or near the breaker box, providing robust protection against both internal and external surges.
Type 3:
Offers extra protection as a point-of-use Surge Protective Device. It must complement Type 1 or Type 2 SPDs to fulfill 2020 code standards.
For optimal protection, integrate Type 1, 2, and 3 SPDs. This layered approach ensures comprehensive defense against power surges.

Selection of SPD:
For a power distribution system, the pivotal characteristics to define the lightning protection system and select an SPD, ensuring the safeguarding of an electrical installation in a building, include:
The additional essential characteristics for selecting an SPD are already predefined for a standard electrical installation.
This sub-section Design of the electrical installation protection system provides an in-depth exploration of the criteria for selecting a protection system tailored to the specific characteristics of the installation, the equipment to be safeguarded, and the surrounding environment.
Location and types of SPD:
Connection of SPD:
Connections of an SPD to the loads should be minimized in length to ensure a reduced voltage protection level (installed Up) at the terminals of the equipment being protected.
The cumulative length of SPD connections to both the network and the earth terminal block must remain under 50 cm.
