Features: *The RCCB provides indirect protection to the operator’s body under such condition that the exposed live parts should be connected to a proper earthing pole.The RCCB also provides protection against the fire danger caused by earth fault current due to function failure of over-current protection device. * RCCB with rated sensitivity up to 30mA could be used as supplementary protecting device in case other protecting device fails its protection against electric shock. * RCCB designed for household installation and other similar application, is for non-professional , and no maintenance is required. *RCCB provides on protection against electric shock resulted from direct contacts of both protected lines,or leakage current between these two lines. *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. Specifications: *Product Name: A TypeResidual Current Circuit Breaker *Material: ABS *Size: As the picture shows *Color: As the picture shows Package Content: 1x A TypeResidual Current Circuit Breaker Note: 1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.
