The Emphatec SigNext - CBM family of circuit breaker modules include single and eight channel versions. The eight channel units have a single input so the module provides power distribution as well. Modules are available for 24Vdc and 120-230Vac applications and the current ratings range from 0.5A to 5A.

The circuit breaker is a supplementaldevice with manual reset. They cannot be tripped manually. Each channel has a status LED – in the case of the single channel versions the LED providestripped breaker indication (on when the breaker is open) while the LEDs provide breaker set indication (on when the breaker is closed) on the eight channel units. The reason for this configuration of the single channel units is to make it interchangeable with fuse terminal blocks.

The interrupting current rating of the breaker is 200A at 24Vdc or 1000A at120-230Vac. In AC applications the modules should be fed from a branch breaker or fuse or from a control transformer that cannot deliver more than 1000A of short circuit current.
