Surge arrester for induced lightning surges
June 2014
Electrical Power & Protection
Saltek’s SLP-275 V/1+1 is a Class 2 combined varistor-based surge arrester and an encapsulated spark gap connected in the 1+1 circuit mode. It is designed for installation in single phase low-voltage distribution boards and switchgear installations at the boundary of LPZ 1 and LPZ 2 zones. The surge arrester protects equipment against the overvoltage effects induced during a lightning strike and switching surges.
The varistor module used between phase and neutral is designed to withstand a peak surge current of 40 kA (8/20) and to limit the voltage to less than 1,25 kV. The gapped arrester used to protect the neutral is designed to withstand peak surge currents of 40 kA (8/20) and limit the voltage to less than 1,25 kV.
All units have DIN rail mounting and the modules are keyed to ensure that live and neutral modules are not interchanged by accident. In addition, the modules are clearly colour coded to ensure easy identification. If required, an optional remote status signalling feature is available in addition to the visual fault signal which is indicated in the glass window.
