Product FAQs

8 answers
Which panelboards accept the BAB2025S circuit breaker?

This bolt-on breaker is designed for Eaton Pow-R-Line, Westinghouse, and Cutler-Hammer panelboards that accommodate BAB-frame Quicklag breakers.

What does the S suffix mean in the BAB2025S catalog number?

The S suffix indicates the breaker includes a factory-installed 120V shunt trip. This allows the breaker to be tripped remotely, which is commonly used for emergency stops or automated control systems.

How is the BAB2025S secured in the panelboard?

It uses a bolt-on connection, fastening directly to the panelboard busbar with screws. This provides a secure, vibration-resistant connection preferred in commercial and industrial environments.

Is the BAB2025S rated for direct current (DC) circuits?

Yes, in addition to its 120/240VAC rating, it is rated for DC applications up to 80VDC. It provides a 5kA interrupting capacity at 24V, 48V, 62.5V, and 80VDC.

What wire gauge range is compatible with the BAB2025S?

The box lugs accept wire sizes from 14 AWG up to 4 AWG. Ensure proper torque specifications are followed during installation.

How does the thermal-magnetic trip unit function on the BAB2025S?

The fixed thermal-magnetic (LI) trip unit uses a bimetallic strip for long-time delay protection against sustained overloads, and a magnetic assembly for instantaneous tripping during severe short circuits.

Can the BAB2025S be used for HVAC equipment?

Yes, Eaton Quicklag BAB breakers from 15A to 100A are HACR rated. This makes the 25A BAB2025S suitable for protecting heating, air conditioning, and refrigeration circuits.

Are Eaton and Cutler-Hammer BAB2025S breakers the same?

Yes. Eaton acquired the Cutler-Hammer brand, so the BAB2025S may be labeled under either name. They are identical in form, fit, and function.

    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.
