Surge Protective Devices (SPDs) are engineered to shield your valuable equipment from transient surge conditions. Such conditions can arise from significant singular events like lightning, with the potential to unleash several hundred thousand volts-posing an immediate risk of failure to your devices. While lightning and external anomalies contribute to 20% of surges, a staggering 80% are internally generated. Though these internal surges are smaller and more frequent, they pose a continuous threat, gradually eroding the resilience of your sensitive electronics.
Product Features
1. Advanced 1P+N phase protection suitable for both AC and DC systems, ensuring comprehensive safety.
2. Comes with a pluggable module, facilitating effortless installation and maintenance, saving time and effort.
3. Boasts a high discharge capacity and rapid response time, offering superior protection against surges.
4. Equipped with dual thermal disconnection devices, this ensures added layers of protection for enhanced reliability.
5. Features a green window indicator that signals faults, while also providing remote alarm control-keeping you informed at all times.
Power surges are brief spikes in voltage that can severely damage electrical devices, often leading to equipment malfunction. Such surges pose a threat to and can degrade the lifespan of:
The National Electrical Manufacturers Association highlights that the average household contains $15,000 worth of equipment susceptible to surge damage.
Common Causes of Surges:
Statistics suggest that 80% of power surges are internally generated.
Internal Sources Include:
External Sources Include:
NEW 2020 National Electrical Code Requirements
Under the 2020 guidelines, all newly built and renovated homes must incorporate Listed and Approved Type 1 or Type 2 Surge Protective Devices to safeguard against surges.
Type 1:
These SPDs are permanently connected and offer protection from both external and internal surges. Versatile in placement, they can be installed indoors or outdoors.
Type 2:
These are permanently affixed near or within the breaker box, defending against internal and external surges.
Type 3:
Provides supplementary protection. As point-of-use devices, they must be used alongside Type 1 or Type 2 SPDs to comply with 2020 code standards.
For optimal protection, it is recommended to use Type 1, 2, and 3 SPDs together, ensuring a robust defense against surges.

Selection of SPD:
For a power distribution system, selecting the right SPD is crucial. The key factors include the characteristics of your lightning protection system and the correct SPD to safeguard your building's electrical installation.
The selection of an SPD involves predefined characteristics tailored to each electrical installation.
This sub-section Design of the Electrical Installation Protection System A comprehensive guide detailing the criteria for selecting the appropriate protection system. It considers the installation's unique characteristics, the equipment needing protection, and the surrounding environmental conditions.
Location and Types of SPD:
Connection of SPD:
Connections of an SPD to the loads should be minimized in length to effectively lower the voltage protection level (installed Up) on the protected equipment's terminals.
Ensure the total length of SPD connections to the network and earth terminal block does not exceed 50 cm.
