Eaton BAB3030H Quicklag Three-Pole Thermal-Magnetic Circuit Breaker, 30A/240V

The Eaton BAB3030H is a Quicklag industrial thermal-magnetic circuit breaker designed to deliver dependable overcurrent protection in commercial and industrial electrical distribution systems. This BAB-type breaker is rated 30A at 240V with a 10 kAIC interrupt rating, giving it the capacity to safely clear fault current while protecting connected equipment and wiring. The three-pole configuration provides balanced protection across multi-phase circuits, while the bolt-on mounting style ensures a secure, vibration-resistant connection to compatible panelboard bus assemblies. With a non-interchangeable trip unit, the BAB3030H is built for fixed, dedicated overcurrent protection, making it a solid choice for electrical contractors and facility maintenance teams specifying Eaton Quicklag breakers for panelboard upgrades, retrofits, and new construction.

Key Features

  • Amperage Rating: 30A rating supports standard-duty branch circuit and feeder overcurrent protection in commercial and industrial applications.
  • Voltage Rating: 240V rating is suited to common low-voltage commercial and industrial power distribution systems.
  • Interrupt Rating: 10 kAIC interrupt capacity allows the breaker to safely clear available fault current without compromising panel integrity.
  • Breaker Type: BAB-type Quicklag thermal-magnetic breaker combines a thermal element for overload protection with a magnetic element for instantaneous short-circuit tripping.
  • Pole Configuration: Three-pole design delivers coordinated protection across all three phases of a multi-phase circuit.
  • Mounting Style: Bolt-on mounting secures the breaker directly to the panelboard bus for a solid, vibration-resistant connection that resists loosening over time.
  • Trip Unit: Non-interchangeable trip unit is factory-set for dedicated overcurrent protection at the specified 30A rating.
  • Series: Part of Eaton's Quicklag line of industrial thermal-magnetic circuit breakers engineered for panelboard compatibility and field reliability.

Eaton BAB3020H – Frequently Asked Questions

1) Will an Eaton BAB breaker plug into a standard load center, or does it need a bolt-on panel?
The BAB Quicklag breakers are bolt-on only. They fasten directly to the panelboard bus with hardware rather than clipping onto a stab, so the panel interior has to be built for bolt-on breakers. If your panel uses plug-in stabs, a BAB will not seat on it and you need the plug-on equivalent instead.
2) Can I use this BAB breaker on a 480V three-phase system?
No. The BAB three-pole Quicklag is rated 240V, which covers 120/240V and 240V three-phase low-voltage distribution. For 480V or 480Y/277V systems you need a breaker rated for that voltage class, not a BAB.
3) I am replacing a breaker in an existing Eaton bolt-on panelboard. Will a BAB3030H match?
If the existing breaker is a BAB-type bolt-on in an Eaton Quicklag panelboard, the BAB3030H is the same mounting style and bus connection, 240V, three-pole, 30A. Check the breaker you are pulling for the BAB prefix and the pole count. Eaton bolt-on families are not cross-compatible, so a BR, QBHW or EHD breaker is not a substitute for a BAB.
4) What amp ratings does the Eaton BAB three-pole Quicklag breaker come in?
Three ratings are offered in the three-pole BAB Quicklag: 20A (BAB3020H), 30A (BAB3030H) and 90A (BAB3090H). All are 240V, bolt-on, three-pole breakers with a non-interchangeable factory-set trip, so the amp rating you order is the rating you keep.
5) Can I change the trip rating on a BAB breaker later if the load grows?
No. The trip unit is non-interchangeable and factory set, so a 30A BAB stays 30A for life. If the load changes you replace the breaker with the next rating up (for example BAB3030H to BAB3090H), assuming the conductors and panel bus support it.
6) Why pick a three-pole breaker instead of using single-pole breakers on each phase?
A three-pole BAB opens all three phases together on a fault, which is what three-phase motor and equipment circuits require. Single-pole breakers on separate phases can leave a motor single-phasing, and that burns windings. Use the three-pole version for any three-phase branch circuit or feeder.
7) What does thermal-magnetic mean on the Quicklag BAB, and is it good for motor loads?
The thermal element handles sustained overloads by heating a bimetal strip, and the magnetic element trips instantly on a short circuit. That combination lets it ride through normal motor starting current while still clearing a bolted fault fast, which is why BAB three-pole breakers get used on motor and equipment circuits in industrial panels.
