Eaton Quicklag BAB Bolt-On Circuit Breaker, Q7 Series

The Eaton Quicklag BAB Bolt-On Circuit Breaker, Q7 Series, spans configurations from a 30A 3-Pole Shunt Trip breaker to a 50A 1-Pole breaker on a single Type BAB bolt-on platform. Every configuration uses the Quicklag thermal-magnetic trip mechanism in a non-interchangeable Q7 series trip unit, backed by a 10 kAIC interrupting rating for reliable fault protection. Select configurations are also rated for use on High Intensity Discharge (HID) lighting circuits, an application requiring breakers with specific trip characteristics, making the BAB series a dependable choice for compatible Eaton load centers.

Key Features

  • Amperage & Pole Range: Available from 30A 3-Pole Shunt Trip to 50A 1-Pole configurations on one bolt-on platform.
  • Bolt-On Mounting: Type BAB bolt-on design ensures a secure, vibration-resistant fit in compatible Eaton BAB load centers.
  • Thermal-Magnetic Trip: Quicklag thermal-magnetic operation combines thermal overload and magnetic short-circuit protection.
  • Interrupting Rating: 10 kAIC short-circuit interrupting capacity for reliable fault protection under industrial loads.
  • Non-Interchangeable Design: Q7 series, non-interchangeable trip unit construction for consistent, code-defined performance.
  • Shunt Trip Option: The 30A 3-Pole configuration adds shunt trip capability for remote or interlocked tripping.
  • HID-Rated: Select configurations are listed for use on High Intensity Discharge (HID) lighting circuits.
  • Type BAB Platform: Built to the Eaton Type BAB miniature circuit breaker platform for straightforward panel compatibility.

Technical Specifications

  • Amperage Rating: 50A
  • Series: Q7
  • Interrupt Rating: 10 kiloamps

Eaton BAB1050 – Frequently Asked Questions

1) Will an Eaton BAB breaker fit a plug-on load center?
No. The Quicklag BAB breakers are bolt-on, meaning they fasten to the bus with a screw rather than snapping on. They need a panel with bolt-on bus provisions for the Eaton Type BAB platform. If your interior is plug-on only, a bolt-on BAB will not seat and you need a plug-on type instead.
2) What does the HS suffix on the Eaton BAB3030HS mean?
BAB3030HS is the 30A 3-pole shunt trip configuration. The shunt trip lets the breaker be tripped remotely, from an external signal or an interlock such as a fire alarm or elevator shutdown, instead of only by overcurrent. It needs control wiring to the shunt coil to do anything; without that it behaves as a standard 30A 3-pole breaker.
3) I'm replacing a failed breaker in an existing Eaton panel. Will a BAB match?
If the panel is built on the Eaton Type BAB bolt-on platform, a BAB breaker of the same amperage and pole count drops into the same bus position. Match three things off the old breaker: type (BAB), amperage, and pole count, plus the shunt trip if the original had control wiring to it. Bolt-on also holds up better where there is vibration than a snap-in connection.
4) What voltage are the Eaton Quicklag BAB Q7 breakers rated for?
120/240V. That covers single-pole 120V branch circuits and 240V two-wire loads on a standard single-phase panel. The 30A 3-pole version is used where three poles are switched together within that same 120/240V rating.
5) Can I use an Eaton BAB1050 on a metal halide or high pressure sodium lighting circuit?
HID lighting ratings apply to select configurations in the BAB Q7 family, not all of them. HID circuits draw a long inrush at startup and need a breaker with trip characteristics that tolerate it, so confirm the specific catalog number you are ordering carries the HID listing rather than assuming it from the series.
6) What amp ratings and pole counts do the Eaton Quicklag BAB Q7 breakers come in?
The range runs 30A to 50A. Two configurations are offered: BAB1050, a 50A single pole, and BAB3030HS, a 30A three pole with shunt trip. Pick by the circuit you are protecting, the 50A 1-pole for a single 120V branch and the 3-pole where you need all three poles to open together.
7) Can I change the trip rating on an Eaton Q7 series breaker?
No. The Q7 trip unit is non-interchangeable, so the amp rating is fixed at the factory and cannot be swapped or field-adjusted. To change the branch circuit rating you order a different breaker. For facilities standardizing a panel schedule, that fixed rating is the point, it keeps the installed protection matching the drawing.
8) How does a thermal-magnetic breaker like the Quicklag BAB protect a circuit?
Two mechanisms in one unit. The thermal element responds to sustained overload, where current runs above rating long enough to heat conductors, and trips on a time delay. The magnetic element reacts instantly to a short circuit or ground fault. That is what the Quicklag industrial thermal-magnetic design in the BAB breakers provides, with faults cleared up to 10 kA.
