Surge arrester 4P, Type 2+3 (class C+D) type V10-C 3+NPE 5094920

Electrical installation protection with surge arresters V10

Surge arrester V10-C 3+NPE is a reliable element protecting electrical installations from the effects of atmospheric and induced surges. Class 2+3 device, marked with the C+D symbol, provides comprehensive protection in TN-S, TN-C-S, TT and TN networks. Its construction based on a pre-assembled base and inserts facilitates installation and ensures readiness for operation immediately after installation.

Construction and application

This arrester is designed for mounting on a DIN TH-35 mm mounting rail and occupies 4 modules. It has optical damage indication, which allows for quick identification of the need for replacement. The use of a thermal and dynamic disconnecting device guarantees safety in case of failure. It is intended for use in residential buildings, single-family homes and other facilities requiring effective protection against surges. The maximum wire cross-section of 35 mm² allows connection of both solid and stranded wires.

Key features and benefits
