ABSTRACT:
A ground fault circuit interrupter against RCE suitable for various electrical instruments, equipments and systems fed by electrical power supply is characterized in that an erroneous reverse connection mechanism is included in its load end and the reset button comprises a reverse trip mechanism. When electric power is mistakenly connected to the load ends, the reset button will be always in trip situation and the socket on its upper lid will be kept free of electricity even the reset is attempted unless the error connection is corrected. As compared to prior art, the circuit interrupter of this invention has a simple mechanical trip structure which can effectively prevent equipment damage and personal hazard caused by reverse connection. Of course, it had successfully passed the 6 KV/3 KA electric surge test and is highly anti-moist and anticorrosive.
