ABB SPER1C1-AAJ Trip Circuit Supervision Relay Brand New ABB Controller Environmental Rating: IP20 (dust protectionSPER 1C1 AAJ Trip Circuit Supervision Relay Overview The SPER 1C1 AAJ supervision relay continuously monitors circuit breaker trip circuits and other essential control circuits in power electrical installations. It is primarily used to supervise critical control and signaling circuits such as those for circuit breakers and disconnectors. Typically, one relay is required per circuit to be supervised. For circuits with multiple branches, multiple relays
