VIB-12 Indoor Vacuum Circuit Breaker With Lateral Operating Mechanism

General Description

Main usage, applying ambient conditions

VIB-12 Indoor Vacuum Circuit Breaker With Lateral Operating Mechanism(Hereinafter referred to as vacuum circuit breaker)are used for 12kV rated voltage and AC 50Hz indoor switch equipment components.The products meet standard of GB 1984-2003 HV ACVacuum Circuit Breaker,JB3855-19963.6~40.5 kV Indoor AC High Voltage Vacuum Circuit Breaker,DLT 403-2000 Order Technical Condition of 12KV~40.5kV Vacuum Circuit Breaker and IEC62271-100:2001 HV AC Vacuum Circuit Breaker,etc.Circuit breaker used as protection and control unit of power design in electric network and industrial and min ingenterprises,can be used for situation of switching various types of load and frequent operation and repeated breaking short circuit current.

This type VCB uses new type operating mechanism of VCB. Embed vacuum interrupter and main circuit's components as a integration by adopting embedded pole of intermnational brand for primary part,so as to protect vacuum interrupter from crash,dust and moist.It has good environmental adaptability,so that reducing operation and maintenance cost greatly and realizing maintenance free of primary part and few maintenance of operating mechanism.The integrated design of operating mechanism and VCB body has passed type test.It has E2 level electrical endurance and M2 level mechanical endurance,used as fixed unit and also with drawable unit by matching specialized push-in mechanism.The fixed type VCB can add corresponding interlock for matching fixed type switchgear of XGN2, GG1A and GGX type.

Applying ambient conditions
