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.
Product scope
Medium voltage circuit breakers with magnetic actuator for primary distribution up to 24 kV, 3150 A (4000*), 50 kA.
