HVD11 vacuum circuit breaker
This product mainly used in 1140v or 660v three phases electrical distribution system. It is used to 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. Its 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.
