gm5fb electromagnetic selective protection of dc circuit breaker-ag凯发k8国际
scope of application
gm5fb series electromagnetic selective protection of dc circuit breaker,is my factory independent research and development,with independent intellectual property rights for dc circuit breaker,suitable for dc rated current 16 a - 800 - a circuit,used for distribution power and protect the distribution circuit and power equipment from overload,the damage of the short circuit fault.the short circuit the short time delay inverse time characteristic with fuse,have good ability of current limit and time delay function,can meet the requirements of power system important load circuit selective protectiondon't rely on electronic circuit short circuit the short time delay function,the reliability of the delay and protection increased substantially.
