Compact Type 3 Surge Arrester for final circuit protection. Install close to low voltage equipment for additional protection. Use with single-phase power supply systems.
Provides audible fault indication.
Benefits: Can be fitted in ducts, trunking or flush type wiring boxes. Provides “fine” protection to individual sockets or circuitsStandards: BS:EN 62305 (Lightning Protection) and EN 61643-11 (Surge Protection Devices).

A lightning surge protection device prevents damage to electrical and electronic equipment from transien over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment.. In a well -designed system, it is important that for each building, both the incoming and outgoing circuits are protected by surge protection devices (where the cables enter and exit the building).This includes:
Field based electronic equipment also need to be protected.
