Eaton / Cutler-Hammer QBHW3035H Miniature Circuit Breaker

This breaker is designed specifically for Eaton and Cutler-Hammer Pow-R-Line panelboards, including the PRL1a and PRL1X series. It requires a bolt-on chassis for installation.

Both are Quicklag bolt-on breakers with identical physical dimensions, but they differ in fault current ratings. The BAB3035 is rated at 10kAIC, whereas the QBHW3035H provides a 22kAIC rating. You can use the QBHW3035H in place of a BAB breaker, but you cannot substitute a BAB if the panel specifies a 22kAIC minimum.

The box lugs accommodate both copper and aluminum conductors. The accepted wire range is 14 AWG to 4 AWG.

No, this breaker is strictly rated for a maximum of 240V AC. If your Pow-R-Line panel requires a breaker for 480Y/277V circuits, you will need to use a GHB series breaker instead.

Bolt-on breakers are mechanically fastened directly to the panelboard bus. This creates a secure, vibration-resistant connection that prevents arcing and maintains continuity in demanding commercial or industrial environments.

It features a thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions. The thermal element responds to sustained overloads, while the magnetic element trips immediately during short-circuit events.
