Product Description

Lightning Current Arresters

FLP-7-V/3+1

FLP-7-V/3S+1

SPD type 1 and type 2

4-pole (3+NPE) arrester for 3-phase TT (TNS) networks Total Iimp= 25 kA (10/350) Varistor lightning and surge current arresters and heavy duty encapsulated spark gap connected in the mode 3+1. To be installed in low-voltage distributions at the boundary of LPZ 0B and LPZ 1 zones to protect distributions and equipment against the overvoltage effects induced during a lightning strike and to prevent switching overvoltage. Optional remote status signalling â€“ version â€žSâ€œ. * Version UC =385 V available on request
