ABB Medium voltage indoor circuit breakers VM1 Breaker AIS ABB MV Products

Medium voltage indoor circuit breakers

VM1 indoor circuit breaker Vacuum and SF6 gas circuit breaker for safe and reliable electrical power distribution or generation in your application up to 46 kV, 4000 A, 63 kA.

Maximize output and productivity with devices that support the continuous operation of your processes, e.g. three times higher mechanical endurance than the standard.

Protect assets with safe and reliable devices, e.g. generator circuit-breaker type tested to the new global dual logo standard (IEC/IEEE 62271-37-013).

Optimize investments with compact devices and high performance, e.g. 17.5 kV/50 kA circuit breaker with 210 mm pole distance.

ABB’s indoor circuit-breakers have been designed to serve your business needs.

With the wide and globally available portfolio we are able to offer you the right fit for the switching of short-circuit currents, overhead lines and cables under load and no load, transformers and generators, motors, ripple control systems and capacitors – even in parallel.

IEC indoor vacuum circuit breaker VM1 Extra performances in demanding duties

VM1 circuit breakers are used in primary power distribution for control and protection of cables, overhead lines, substations, motors, transformers, generators, capacitor banks, etc. in plants in chemical industries, steelworks, automobile industries, airports, large buildings and shopping malls. The magnetic drive activates the moving contacts of the interrupters and integrates all the functions of a traditional drive.
