Product Description

High Voltage Circuit Breaker

Main Features of High Voltage Circuit Breaker

LW35-72.5/126/145 circuit breaker is either three-phase gang operation with a sping mechanism or single-phase operation with three spring mechanism.

LW35-252 circuit breaker is equipped with three spring mechanisms to realize single-phase operation or three-phase electrical gang operation.
