Legrand surge arrester insert B+C 8kA 320V

The Legrand 412302 is a plug-in replacement module designed for surge protective devices (SPD) with combined Type 1 and Type 2 protection, capable of handling surge currents of 8 kA per pole. It is engineered to protect electrical installations against transient overvoltages, ensuring the safety and longevity of connected equipment.

This module supports system configurations TN and TN-C, including TN-C-S, and other systems, providing versatile compatibility. It operates at a nominal AC voltage of 400 V with a maximum continuous voltage of 320 V. The voltage protection levels are 2 kV between line and neutral (L-N) and 1.5 kV between neutral and protective earth (N-PE), offering effective surge suppression.

Featuring optical signalling for status indication, the device does not include an integrated backup fuse but offers residual current circuit breaker protection with overload. The construction size is compact, occupying 1 modular spacing, and it has an IP20 degree of protection, suitable for indoor electrical panels.

Ideal for installation in mounted boxes, this module is a reliable choice for upgrading or replacing surge protection components in commercial or residential electrical systems. It is distributed by authorized wholesalers and is identified by EAN 3414970518347 and model number 412302.
