6P.14.8.320.1012

The Finder 6P.14.8.320.1012 is a Type 1+2 surge protection device designed for three-phase AC installations with neutral in TT and TN-S earthing systems. Its 3+1 configuration uses three replaceable varistor modules for L-N protection and an encapsulated spark-gap module for N-PE protection. This arrangement helps manage surge currents associated with direct or indirect lightning strikes and switching overvoltages.

The device is intended for installation at the boundary between LPZ 0 and LPZ 1 and is suitable for 35 mm EN 60715 DIN-rail mounting. It includes visual status indication, while remote status signalling is optional. The Finder catalogue lists a nominal discharge current of 40 kA L-N and 50 kA N-PE, with maximum discharge currents of 80 kA and 100 kA respectively. Confirm the supply system, upstream fuse protection and module requirements with a qualified electrical professional before installation.
