SONTUOEC Residual Current Circuit Breakers RCCB, RCD 2 pole 25A 4pole 100A 30mA 100mA 300mA 4p and 2p
ACT264/464 series Residual Current Circuit Breaker provide the function of isolation switching and earth leakage protection of electrical circuits. And also provide the indirect protection of the operator's body against the dangerous effects of electric current and provide the protection of the fire caused by the electrical circuit fault.
- Our products have the guarantee period of 36 calendar months,that is a high quality and reliability;
- Our products have an excellent ratio between price and quality ,you can possess them by competitive price and high quality;
- The fast and flexible production form aim at the customer require;
- The deliveries exactly in accordance with customer orders
- The fast transportation.
- Adopt electromagnetic style release , can play a leak electricity and electric shock protecting role while breaking in zero Line.
- Measuring component and buckling component of products is located between enter line end and entrance line end ;
- Movement characteristic of products can not be changed with outside mechanical tool;
- The operating organization has the free function to take off and buckle;
- Operate part can not be taken down from the shell outer of products , the shell can not influence the operating organization to work , the accessory group which replace the feelers pressure, should guarantee the feelers pressure does not change while running.

1. SONTUOEC RCCB with rated sensitivity up to 10mA, 30mA ,100mA,300mA could be used as supplementary protecting device in case other protecting device fails its protection against electric shock.
2. SONTUOEC RCCB designed for household installation and other similar application, is for non-professional operation, and no maintenance is required.
3. SONTUOEC RCCB provides no protection against electric shock resulted from direct contacts of both protected lines,or leakage current between these two lines.
4. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to RCCB as precaution against potential surge voltage and current occurring at its power input side.
5. Satisfying conditions and applications as mentioned above,SONTUOEC RCCB with °∞ON-OFF°± indicating device is considered suitable for isolation function.
