Electronical Vacuum Circuit Breaker (VCB)

Electronical Vacuum Circuit Breaker (VCB). Structural features: three-phase independent pillar structure, air insulation, vacuum arc extinction, breaking short-circuit current 20kA up to 30 times. Modular design: Adopts the modular design concept, and the combination mode of electromagnetic/electronic sensors can be flexibly interchanged. State monitoring: It supports the collection of analog and state quantities monitoring, remote signaling anti-shake, on-site indication of operating state, communication state, line fault state, etc. Protection function: Accurately judge and quickly Isolate short-circuit faults, ground faults, and broken line faults. Intelligent terminal: It has functions such as line loss collection, feeder automation, communication, positioning, timing and recording, power management, etc., and supports remote maintenance, etc. High adaptability: Suitable for high-altitude, highly polluted, highly condensed, highly salt spray, and severe cold regions.
