WSP240/I/TT (Mains, Type 1 & 2)

Single phase Type 1 and 2 tested (BS EN 61643) surge protector for use primarily on mains power distribution systems to protect connected equipment from transient overvoltages.

Designed for use at the boundaries of LPZ 0a to LPZ 2 as part of a coordianted SPD system (BS EN 62305), this type of protection is usually used for equipotential bonding in structures that have a Lightning Protection System (LPS) fitted, at the point cables enter the structure (LPZ 0a or b to LPZ 1 boundary).

Features and Benefits:

  • Repeated protection in lightning intense environments.
  • Per-phase remote signalling contacts allow surge protection status to be monitored via a building management system.
  • Thermal disconnect for safe disconnection from abnormal or faulty supplies.
