Eaton / Cutler-Hammer BABRSP2040 Miniature Circuit Breaker

This bolt-on breaker is designed for use in Eaton Pow-R-Line, Westinghouse, and Cutler-Hammer panelboards. It is frequently installed in Pow-R-Command lighting control and energy management systems.

The RSP suffix indicates this is a remotely operated Smart Breaker with a built-in status switch. It contains an integral solenoid that allows the breaker to be pulsed on and off remotely, while the status switch provides feedback to a controller or PLC.

The breaker includes color-coded pigtail wires for remote operation. The blue wire provides power input, the black wire is for remote opening, the red wire is for remote closing, and the yellow wire provides status feedback to indicate if the contacts are closed.

No. The solenoid-controlled contacts are wired in series with the thermal-magnetic breaker mechanism. If the breaker handle is in the OFF or tripped position, closing the remote contacts will not energize the load.

Yes. The breaker features a manual override lever that allows you to close the operator contact locally. A red indicator shows when the remote contacts are closed. However, once closed manually, the contact can only be reopened by a remote signal.

The external load current on the yellow status feedback wire must not exceed 0.5 amps.

Always turn the mechanical breaker handle to the OFF position before servicing equipment, regardless of the remote contact status. Relying solely on the remote contacts is unsafe, as they could close unexpectedly if a control signal is received.

Yes. Any combination of remotely operated smart breakers and standard branch circuit breakers can be installed in the same compatible panelboard chassis without requiring additional mounting structures.
