Application
Application of residual current circuit breakers are mainly used to protect residential,functional industrial buildings and hotel etc.System AC 230/415V and rated current from 10A to 63A it is found widely used to protect residential,functions,industrial buildings and hotel etc.Against earth leakage .insulation fault and fire accident caused by direct or indirect contact with electric parts(including human of other animal getting a electric shock).it will trip free under rated value,or current delay angle of 0°,90°,135°residual pulsating direct current,or pile pulsating direct current up to 0.006A direct current,It is compatible with normal RCCB
Construction features
-Measuring component and bucking 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 organizations to work, the accessory group which replace the feelers pressure,should guarantee the feelers pressure does not change while running.
