Panel Compatibility

The Eaton BQL370 is a bolt-on style breaker from Eaton's BQL series, designed to mount in compatible Eaton/Cutler-Hammer bolt-on panelboards — typically commercial-grade loadcentres and panelboards that accept the BQL bolt-on frame. It is not a plug-in (BR or CH clip-in) type and will not interchange with Eaton's BR or CH plug-in panels.

At 3-pole / 240V / 70A / 10kA AIC, this breaker suits three-phase or single-phase commercial distribution panels rated for bolt-on breakers of this frame size. Have your panel model handy — send us your panelboard model and we'll confirm fitment.

The BQL series uses a bolt-on mounting mechanism, meaning the breaker is physically bolted to the bus bar rather than clipping in. This provides a more secure connection and is typically specified for commercial panelboards. It is not interchangeable with Eaton's BR or CH plug-in style breakers, so it's important to verify your panel accepts bolt-on breakers before ordering.

The BQL370 is primarily designed for commercial bolt-on panelboards. While Eaton describes it as suitable for certain heavy-duty residential applications, most standard residential loadcentres use plug-in (BR or CH) breakers. If you're unsure whether your panel accepts bolt-on breakers, contact our team with your panel model and we'll help confirm compatibility.
