CBS – Circuit Breaker Supervisor
Nowadays there is an increasing concern about the electric system reliability. All the essential equipment must be monitored continually so that the system can operate with minimum interruptions.
The circuit-breakers and blocking relays are some of these essential assets, so they have to be maintained in operational condition to perform in case of serious faults that can causepermanent systemdamage.
The Circuit Breaker Supervisor – CBS was developed to provide continuous supervision of the status of opening and closing coils of circuit breakers and blocking relays in electrical systems verifying their continuity.
A CBS can supervise up to three coils, (ie. Two opening coils and one closing coil) and the auxiliary power supplyvoltage, with separate contacts to signal each event.
The 3 coil supervision circuits are galvanically insulated from each other, enabling the monitoring of coils fed by different voltage sources or coils from different circuit breakers in one CBS.
The CBS can operate with an auxiliary voltage from 85 to 265 Vdc/Vac and monitor coils fed with voltages between 80 and 300 Vdc.
Due to its compact dimensions and its mounting method on 35mm DIN rail, the CBS can be easily installed in the circuit breaker control panel.
