Eaton RVS-3PHAS/125 Type 1+2 Surge Arrester 3-Phase 125 kA DIN Rail 215617

3-phase surge arrester with combined Type 1+2 protection, delivering a total impulse current of 125 kA (10/350 µs) per pole to safeguard low-voltage power distribution systems against direct lightning strikes and switching overvoltages.

Advantages

High discharge capacity of 125 kA ensures robust protection for industrial and commercial installations. Visual status indication (green/red) allows quick on-site checking without additional tools. Compact 4-module DIN rail design simplifies installation in standard distribution boards.
