Product Description
Timetric Embedded Poles Type VCB Introduction
Embedded Poles Type VCB is an indoor switchgear for three-phase AC power system with rated voltage of 24kV and 50Hz, as the protection and control unit of power grid equipment and power equipment in industrial and mining enterprises. It is suitable for frequent operation at rated working current, or many times to break the short circuit current.
The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as the fixed installation unit and also equipped with a special propulsion mechanism to form the role of the handcart unit.
