Eaton Quicklag BAB Series Two-Pole Thermal-Magnetic Circuit Breaker

The Eaton Quicklag BAB Series Two-Pole Thermal-Magnetic Circuit Breaker is a family of industrial thermal-magnetic breakers engineered for dependable overcurrent protection in commercial and industrial electrical distribution systems, available in amperage ratings from 15A through 80A across the BAB2015, BAB2020, BAB2040, BAB2060, and BAB2080 models. Every breaker in the series is rated for 240V across two poles and carries a 10 kAIC interrupt rating, giving it the capacity to safely clear short-circuit currents while protecting downstream branch circuits and connected equipment from sustained overloads. Each model uses a bolt-on mounting configuration, allowing it to be securely fastened directly to the bus of a compatible panelboard rather than simply plugged in, which helps maintain a tight, vibration-resistant connection in demanding industrial environments. As part of Eaton's BAB / Q7 platform, these breakers are built with a non-interchangeable trip unit fixed to each model's specific amperage rating for consistent, predictable performance.

Key Features

  • Amperage Range: Available in 15A, 20A, 40A, 60A, and 80A two-pole models sized for branch-circuit and feeder overcurrent protection in commercial and industrial panelboards.
  • Interrupt Rating: 10 kAIC short-circuit interrupt rating shared across the series gives the fault-current withstand capacity required for demanding industrial and commercial services.
  • Voltage Rating: Rated at 240V across two poles, suitable for standard single-phase and multi-wire branch circuits found in commercial and industrial 240V systems.
  • Bolt-On Mounting: Bolt-on mounting style bolts directly to the panelboard bus bar for a secure, vibration-resistant connection well suited to industrial settings subject to shock and movement.
  • Thermal-Magnetic Trip Mechanism: The Quicklag thermal-magnetic trip combines a thermal element for sustained overload protection with a magnetic element for fast-acting short-circuit tripping.
  • Two-Pole Configuration: Two-pole design allows each breaker to simultaneously interrupt both ungrounded conductors of a 240V circuit for complete disconnection.
  • Series & Trip Type: Part of Eaton's BAB / Q7 series with a non-interchangeable trip unit fixed to each model's amperage rating, ensuring consistent protection coordination.

Eaton BAB2020 – Frequently Asked Questions

1) Will an Eaton BAB2020 bolt-on breaker fit a plug-in load center?
No. The Quicklag BAB two-pole breakers are bolt-on only, meaning they fasten directly to the panelboard bus rather than clipping on. If your panel bus is prepped for plug-in breakers (Eaton BR style, for example), a BAB will not seat. You need a panelboard whose bus accepts Eaton's BAB / Q7 bolt-on interior.
2) Can I use a BAB two-pole breaker on a 208V or 240V single-phase circuit?
The BAB two-pole breakers are rated 240V, which covers standard 240V single-phase and multi-wire branch circuits as well as two legs of a 208Y/120 three-phase system, since each leg is below the 240V rating. Both ungrounded conductors are interrupted at the same time by the common trip.
3) I'm replacing a failed breaker in an Eaton panel. How do I confirm a BAB is the right replacement?
Match three things on the breaker you are pulling out: the BAB / Q7 bolt-on mounting style, the 240V two-pole configuration, and the amp rating stamped on the handle. If the existing unit reads BAB2 plus an amp number, the matching BAB2015, BAB2020, BAB2040, BAB2060 or BAB2080 drops into the same bus position. Also confirm the panel's interrupt requirement is 10 kA or less.
4) What amp sizes does the Eaton Quicklag BAB two-pole breaker come in?
Five two-pole ratings: 15A (BAB2015), 20A (BAB2020), 40A (BAB2040), 60A (BAB2060) and 80A (BAB2080). The 15A and 20A sizes cover 240V branch circuits like baseboard heat and small equipment; 40A through 80A are typically used for larger equipment and sub-panel feeders.
5) Can the trip rating on a BAB breaker be changed in the field?
No. The trip unit is non-interchangeable and fixed to each model's amperage rating, so the amp size is decided when you order. To change a circuit's protection you swap the whole breaker, for example moving from a BAB2040 to a BAB2060.
6) What does thermal-magnetic mean on a Quicklag breaker, and is it right for motor loads?
The Quicklag trip has two elements: a thermal element that responds to sustained overload over time, and a magnetic element that trips fast on a short circuit. That combination rides through normal motor inrush while still clearing a bolted fault quickly, which is why the series is used for motor and equipment branch-circuit protection as well as general feeders.
7) Why pick a bolt-on breaker over a plug-in one for an industrial panel?
Bolt-on breakers are fastened to the bus with screws instead of relying on a spring clip, so the connection stays tight where there is vibration, shock, or thermal cycling, common in industrial plant rooms and on equipment skids. Plug-in breakers are quicker to change out but depend on clip tension. The BAB series is bolt-on, so plan on pulling the deadfront and using a screwdriver for every change.
8) Is the Eaton BAB two-pole breaker suitable for standardizing breaker stock across a facility?
It works well for that if your panelboards are Eaton BAB / Q7 bolt-on. One 240V, 10 kAIC, two-pole platform covers 15A through 80A, so a maintenance crib can stock five part numbers (BAB2015, BAB2020, BAB2040, BAB2060, BAB2080) and cover most two-pole branch and sub-feeder needs without mixing trip platforms.
