Product FAQs

8 answers
What panelboards are compatible with the BABRSP2040 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.

What does the RSP designation mean on this BAB frame breaker?

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.

How are the remote control and status wires configured on the BABRSP2040?

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.

Will the remote contacts supply power if the breaker handle is in the tripped position?

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.

Can the BABRSP2040 be operated manually without a remote signal?

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.

What is the maximum allowable current on the status feedback wire?

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

How should the circuit be de-energized before performing maintenance?

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.

Can this smart breaker be installed alongside standard breakers in the same panel?

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.

    Excellent Experience

    We placed our first order with superbreakers.com recently for a breaker we weren't able to acquire locally. I ordered the breaker way ahead of time because I've had issues with shipping for products purchased online in the past. The estimate for the item when I initially ordered was 3 days. Without adding an expedited shipping options, the breaker arrived the next day. We installed it this week, and so far so good. In my opinion, they sell quality parts and have excellent turn around time. Very impressed.
