Eaton / Cutler-Hammer BAB2035 Miniature Circuit Breaker

The BAB2035 is engineered for Eaton Pow-R-Line commercial panelboards. Because the Quicklag form factor has remained consistent for decades, it is also fully backwards compatible with legacy Westinghouse, Cutler-Hammer, and Bryant bolt-on panelboards.

Yes, this Eaton breaker is a direct form, fit, and function replacement for legacy Westinghouse and Bryant BAB2035 circuit breakers, as well as QNBL2035 models.

Both are 35-amp, 2-pole Quicklag bolt-on breakers with identical dimensions. The difference is the short circuit interrupting rating. The BAB2035 has a 10kAIC rating, while the QBHW2035 is rated for 22kAIC. You can substitute a QBHW2035 if your electrical panel requires a higher fault current rating.

This is a bolt-on circuit breaker. The load side is equipped with box lugs for the branch circuit wiring, while the line side features an extended tang that bolts directly onto the panelboard bus for a secure mechanical and electrical connection.

No. The BAB2035 has a 120/240VAC slash rating, which means it is only approved for use in solidly grounded systems where the nominal voltage to ground does not exceed 120V. It cannot be used on straight 240V ungrounded or corner-grounded delta systems.

Yes. Like all modern 15-amp through 100-amp Quicklag BAB breakers, it carries an HACR rating, making it approved for overcurrent protection in heating, air conditioning, and refrigeration equipment circuits.

Proper torque prevents thermal failures. For these Quicklag box lugs, typical torque values are 21 lb-in for 14 to 12 AWG, 25 lb-in for 10 to 8 AWG, and 36 lb-in for 6 to 4 AWG wire. Always verify the exact specification printed on the breaker label before terminating conductors.

No, this breaker is designed strictly for commercial and industrial bolt-on panelboards. It will not fit or mount into residential plug-on load centers such as the Eaton BR or CH series.
