2P AC Surge Protector 385V 40kA - Full Mode L-N/L-PE/N-PE SPD for Residential & Industrial Circuits

The SPD-AC-2P-Grey is a 2-pole AC surge protection device providing full-mode protection across all three paths – L-N, L-PE, and N-PE – in a single module. This comprehensive coverage ensures that single-phase electrical devices and precision instruments are shielded from surge transients regardless of which conductor the overvoltage appears on. The maximum discharge current is 40kA with a nominal of 20kA, and the voltage protection level is kept at – .0kV. At its core, a metal oxide varistor (MOV) responds in under 25 nanoseconds for instantaneous suppression. Compatible with single-phase AC and IT systems, the SPD-AC-2P connects via L (In/Out) and N (In/Out) terminals and clips onto a standard 35mm DIN rail. The grey flame-retardant PC housing (UL94 V-0) features a modular, hot-swappable design for maintenance without rewiring. Suitable for main distribution boxes, sub-distribution boxes, and small industrial circuit panels.
