Fault detection device according to the operation signal given rapidly and reliably cut off the power

When the system fails, it can according to the fault detection element given action signal, quickly and reliably cut off the power, and a low-pressure release function, and  electri cenergy meter  of electrical combinations make all kinds of electromagnetic launcher. AC contactor mcb circuit breaker is simple, variety, work performance, use of large, wide range of applications. In the low-pressure system has a large  circuit breakers  of energy through the exchange of contacts assigned to a variety of electrical devices. Large, medium and small capacity AC contactor retention time in the active power consumed even hundreds of watts to tens of watts.
