  • Page 19: Circuit Breaker Failure Protection (Cbfp)

    The breaker failure function is activated if the EAFR-101 detects the presence of light after a set operating time. When EAFR-101 is set to operate on light and current, EAFR-101 both parameters must persist to activate CBFP . Breaker fail- ure can be set to operate either on 100 ms or 150 ms delay (Section 3.5: Dipswitch Settings).
