Eaton Quicklag BAB Series Two-Pole Bolt-On Circuit Breakers, 25A–125A

The Eaton Quicklag BAB series is a family of industrial thermal-magnetic circuit breakers engineered for dependable branch circuit protection in industrial and commercial electrical systems. These two-pole breakers are rated for 120/240V AC service with a 10 kAIC interrupt rating, giving installers a breaker sized for demanding branch circuit and feeder applications. Every breaker in this listing uses bolt-on mounting to secure directly to compatible panelboard bus assemblies, providing a stable, vibration-resistant connection for long-term panel performance. The thermal-magnetic trip mechanism is a non-interchangeable, fixed Q7 series design, meaning trip characteristics are factory-set and cannot be swapped in the field, supporting consistent, predictable overcurrent protection. Select your required amperage from the options above.

Key Features

  • Bolt-On Mounting: Secures directly to compatible panelboard bus bars for a solid, vibration-resistant connection in industrial installations.
  • Two-Pole Configuration: 2-pole design supports 120/240V AC circuits requiring dual-leg overcurrent protection.
  • Multiple Amperage Ratings: Available in 25A, 35A, 45A, 50A and 125A to match the branch circuit you are protecting — choose your rating from the options above.
  • 10 kAIC Interrupt Rating: Thermal-magnetic trip mechanism is rated to interrupt fault currents up to 10,000 amps, helping protect downstream equipment and wiring.
  • Non-Interchangeable Trip Unit: Fixed Q7 series trip design maintains factory-calibrated protection and helps prevent unauthorized field modification of trip settings.
  • Thermal-Magnetic Protection: Combines thermal response for sustained overloads with magnetic response for short-circuit conditions.
  • Quicklag Industrial Series: Part of Eaton's Quicklag BAB line of industrial-grade thermal-magnetic circuit breakers built for demanding panelboard environments.
  • 120/240V AC Rating: Suited for standard single-phase industrial and commercial distribution voltages.

Eaton BAB2025 – Frequently Asked Questions

1) Will an Eaton BAB two-pole breaker plug into my existing load center, or does it bolt on?
The BAB Quicklag two-pole breakers are bolt-on, not plug-on. They fasten directly to the panelboard bus assembly, so the panel has to be a bolt-on style panelboard with tapped bus. If your load center takes plug-in breakers, a BAB will not seat in it and you need a plug-on type instead.
2) Is a 10 kAIC breaker enough for my panel?
The BAB two-pole breakers carry a 10,000 amp interrupting rating. That covers most branch panel locations fed well downstream of the service, but if your fault current calculation at that panel exceeds 10 kA, the breaker is not rated for the location and you need a higher AIC device or series-rated assembly. Get the available fault current at the bus before you commit.
3) I need to replace one bad breaker in an older industrial panel. Will a BAB2050 match?
If the panel is a bolt-on Eaton panelboard already populated with BAB breakers, a BAB2050 is a like-for-like two-pole 50A replacement, same bolt-on bus connection and same 120/240V AC, 10 kAIC ratings as its siblings. Check the panel's label for the breaker types it is listed to accept; bolt-on breakers are specific to the bus they are tapped for.
4) What amperages does the Eaton BAB two-pole Quicklag breaker come in?
Five two-pole ratings: 25A (BAB2025), 35A (BAB2035), 45A (BAB2045), 50A (BAB2050) and 125A (BAB2125). All are 120/240V AC rated with the same bolt-on mounting, so you can standardize a panel on BAB and just change the trip rating per circuit.
5) Can I adjust or swap the trip unit on an Eaton BAB breaker?
No. The BAB uses a fixed, non-interchangeable Q7 series thermal-magnetic trip. Ratings are factory calibrated and cannot be changed in the field, so if a circuit's load changes you replace the whole breaker with the correct amperage rather than re-rating the one in the panel.
6) Can I use a two-pole BAB breaker for a 240V piece of equipment like a heater or compressor?
Yes, that is the intended use. The two-pole configuration lands both hot legs for 120/240V AC single-phase circuits, and the line is called out for motor and equipment feeder protection as well as general branch circuits. Size the pole rating to the equipment nameplate and conductor ampacity.
7) What does thermal-magnetic mean on this breaker, and is it the right type for my branch circuits?
Two trip mechanisms in one device: a thermal element that responds to sustained overload and a magnetic element that trips fast on a short circuit. That is the standard choice for branch circuit and feeder overcurrent protection in commercial and industrial panelboards, which is what the BAB Quicklag line is built for. It is not a ground-fault or arc-fault device, so if code requires GFCI or AFCI protection on that circuit you need a different breaker type.
