Product Detail

VCB Vacuum Circuit Breaker 1.14KV 630A 15KA HVD11 from JUCRO Electric


General

HVD11-1.14 Vacuum Circuit Breaker is mainly used in 1140v or 660v three phases electrical distribution system. It is used for distribution power, circuit protection and power equipment. It is also popular in railway, mine, electricity and so on. The product structure is vertical design. Vacuum chamber, electromagnet and latched device is up-down structure. Adjustment and maintenance are easy. It has high breaking ability, high reliability and long working life. It is in and out bus bar is at the back of the circuit breaker. And the bus bar is plug-in type, can be installed as explosion-proof feed switch easily. This circuit breaker should be used together with electronic tripper.
