Scope of application
SRB9E series loT circuit breakers are mainly used in power distribution networks with AC 50Hz,rated working voltage of 400V, and rated current up to 800A. They are used to provide indirect contact protection for people, and can also be used to prevent ground faults due to equipment insulation damage. It can be used for the fire hazard caused by the current, can be uesd to distribute electric energy and protect the overload and short circuit of the line into the power supply equipment.
