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.
A ground fault circuit interrupter against reverse connection error(RCE) mainly comprising an outer case consisted of a base (003), a middle frame (002), an upper lid (001) on which is installed a reset button (006) and a test button (007), a grounding frame (004), two input ends and two load ends, and two socket static contact conducting parts (005-1, 005-2), wherein the said two input ends include respectively an input end movable contact (016, 017) connected by wire, the said two loads end include respectively a movable contact (018, 019) connected by wire and an erroneous reverse connection mechanism, the and said reset button (006) includes a reverse trip mechanism.
