Product Description

Product Description

This series vacuum circuit breakers are three-phase AC 50Hz indoor high-voltage switchgear with rated voltage of 12kV-40.5kV.
The operating mechanism of the circuit breaker is spring energy storage type, which can be operated by AC or DC or manually.
The circuit breaker has a simple structure, strong breaking capacity, long service life, complete operating functions, no danger of explosion and simple maintenance. It is suitable for power control or protection switching transmission and distribution systems, such as power plants, substations and industrial and mining enterprises, and is especially suitable for important loads and places of frequent operation.
The installation form of circuit breaker in the switch cabinet can be fixed or handcart type.
This product conforms to GB1984, JB3855, IEC62271-100 and other related standards.
