Product description

SMG-VS1-12 permanent magnet indoor high voltage vacuum circuit breaker, the three-phase AC 50Hz rated voltage of 12KV power system indoor switching equipment, as the power grid equipment, industrial and mining enterprises power equipment protection and control unit. Applicable to require the rated current in the frequent operation, or a number of places breaking short-circuit current. The circuit breaker using the operating mechanism and the circuit breaker body-in-one design, either as a fixed installation unit, can also be equipped with a dedicated propulsion body, composed of hand-car unit.

Model and meaning

Performance advantages

This type of product with bistable permanent magnet operating mechanism, the body is equipped with permanent magnets. The holding force is provided by the permanent magnet. So that the switch maintained in the closed state, compared with the conventional spring-operated mechanism, a large number of mechanical parts to reduce the mechanical transmission chain shortened, so that the reliability of a substantial increase in the switch, a substantial increase in mechanical life.
