Description
Integrating remote shutdown capabilities, this 70A miniature circuit breaker includes a factory-installed 120/208/240VAC shunt trip mechanism. It fastens securely into Eaton Pow-R-Line and legacy Westinghouse panelboards. Because of the added accessory, this specific model requires a wider 3.2-inch footprint compared to standard two-pole versions, replacing older QNBL shunt-trip units. The thermal-magnetic design provides a 10kAIC rating and carries full HACR certification for HVAC loads.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the BAB2070S circuit breaker?
This bolt-on breaker is designed specifically for Eaton Pow-R-Line panelboards and legacy Westinghouse panelboards. It secures directly to the bus bar and will not fit in standard plug-on residential load centers.
What is the difference between the standard BAB2070 and the BAB2070S?
The "S" suffix indicates that the BAB2070S includes a factory-installed shunt trip mechanism, allowing for remote shutdown of the breaker. Because of this added accessory, the BAB2070S requires a wider 3.2-inch footprint in the panel compared to the standard two-pole BAB2070.
Can the BAB2070S replace older discontinued shunt-trip breakers?
Yes, this model serves as a direct substitute for older, discontinued QB and QNBL series shunt-trip units in compatible Cutler-Hammer and Westinghouse enclosures.
Is the BAB2070S suitable for HVAC equipment loads?
Yes, Eaton Quicklag BAB breakers from 15A to 100A carry a full HACR certification, making this 70-amp breaker fully approved for heating, air conditioning, and refrigeration applications.
Can this breaker be used in DC voltage systems?
Yes, while it provides a 10kAIC rating for standard 120/240VAC systems, the BAB2070S is also rated for DC circuits. It delivers a 5kAIC interrupting capacity across 24V, 48V, 62.5V, and 80VDC applications.
What wire sizes are accepted by the BAB2070S box lugs?
The breaker's terminals accommodate both copper (Cu) and aluminum (Al) conductors ranging from 8 AWG up to 1/0 AWG. Always ensure connections are torqued to the manufacturer's specifications during installation.
How does the thermal-magnetic trip mechanism function on this breaker?
The fixed thermal-magnetic (LI) trip unit offers dual-level safety. The thermal component provides long-time protection against sustained overloads, while the magnetic component delivers instantaneous tripping to safely clear high-level short circuits.

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.
