Product Description

Product details:
Description:
The ZN85-40.5/T2000-31.5 indoor HV vacuum breaker(short for breaker)is used for switching on/off load current, over load current, fault current in industrial and mining establishments, power plants and transformer substations with three-phase AC 50HZ,rated voltage 40.5KV power system.
The breaker and operating mechanism use up-under arrangement stucture, reducing the depth of the breaker effectively.
With reasonable general planning, goodly and compact outline, small size and flexible operation, the break has features of reliable electric specification, long life, easy to check and non-maintenance of the mechanism.
The breaker is used for operating frequently and in some places with difficult working conditions
