Medium Voltage Switchgear
Vacuum Circuit Breaker(VCB)
Features
Performance
Insulation recovery characteristics in vacuum are fast and arc time is short so wear on main contacts is low and service life is long.Also, a high-speed circuit breaker is used for reclosing.
Compact and lightweight operating mechanism combines new vacuum valve format and delivery history of 700,000 vacuum switchgear.
VZ type circuit breaker has acquired KEMA and CESI certification.
Safety
Electric performance and mechanical construction that complies with JEC-2300(1998), IEC 60056(1987).Can be equipped with grounding mechanism inside the switchgear and mechanical interlock on the door.
Quality control system is integrated from design to production and testing.
Maintainability
Circuit breaker uses high-reliability vacuum valve.Operating mechanism is low-fault factor mechanism mounted on the front for long service life and easy maintenance inspections.
Environmental considerations
No environmentally dangerous materials are used.Low noise when current is stopped.
