The SBF-1 is a solid state breaker failure detection relay with contact output. It is used in conjunction with primary and backup relays. Other logic inputs (such as the 52a contact) may be used where the fault current is insufficient to operate the current detector.
The relay is applicable with any bus/breaker schemes in general use.
