Tree Tech Model CBS
The Circuit Breaker Supervisor (CBS) was developed to provide continuous supervision of the status of open and close coils of circuit breakers, block relays in electrical systems and verification of their continuity.
 
A CBS can supervise up to three coils, (i.e. two open coils and one close coil) and the auxiliary voltage of the power supply, 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 assembly method in U-type rails, the CBS can be easily installed even in the circuit breaker control panel.
