Product Description

Description

indoor permanent magnet solid-sealed high-voltage vacuum circuit breaker is an indoor switchgear of a three-phase AC 50Hz rated voltage of 12KV power system, used as power grid equipment, industrial and mining enterprises
Protection and control unit for industrial power equipment. It is suitable for places requiring frequent operation under rated working current, or multiple interruption of short-circuit current.
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.

Use environmental conditions
This type of product is equipped with a bistable permanent surface mechanism. The mechanism is equipped with permanent magnets. The permanent magnets provide the holding force to maintain the switch in the closed and open state. Compared with the conventional spring operating mechanism, the number of mechanical parts is greatly reduced. The mechanical transmission chain is shortened, so that the reliability of the switch is greatly improved, and the mechanical life is greatly increased.
