Rccb sensitivity selection
Webof its high sensitivity to earth fault current and its rapid operating time, in most cases the RCCB will ensure disconnection within the speciied time. This is achieved without any detriment to overcurrent discrimination because, unlike the situation in a fuse based system, the increased sensitivity is obtained without increasing sensitivity to
