HVD11-1.14 INDOOR HIGH VOLTAGE VACUUM CIRCUIT BREAKER
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.
本产品主要用于1.14KV或660V三相电网中, 用于分配电能,保护线路及电源设备,广泛用于铁路,矿山,电力部门.产品主体结构为立式设计,开关管与电磁铁,锁扣机构按上下结构.调整,维修很方便,分断能力强,可靠性高,使用寿命长.其进出母线排在断路器后侧,为插接式设计,可方便地组成隔爆型馈电开关.本断路器应与电子脱扣器配合使用.
