Product Description

Ebery factory VCB-12 11kv 13.8kv vcb indoor switchgear High Voltage Vacuum Circuit Breaker

Overview:
VBR (VS1)-12 permanent magnet type indoor high voltage vacuum circuit breaker is an indoor switch device with three-phase AC 50Hz rated voltage of 12kV power system. It is used as protection and control unit for power equipment and industrial and mining enterprise power equipment. It is suitable for places that require frequent operation at rated operating current or multiple short-circuit currents.
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, and can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit.
Performance advantages:
This type of product is equipped with a single (double) steady-state permanent magnet operating mechanism. The mechanism is equipped with a permanent magnet. The permanent magnet provides the holding force to maintain the switch in the closing and opening state. Compared with the conventional spring operating mechanism, the number of mechanical parts A large number of reductions and a shortened mechanical kinematic chain have greatly improved the reliability of the switch and greatly increased the mechanical life.
