Not sure if this breaker fits your panel? Send us your panel model number and we'll confirm compatibility.

The BR140 is designed for Eaton BR-series (Type BR) residential loadcentres and panelboards. It uses a plug-in (push-in) connection to the bus bar. It is NOT compatible with Eaton CH-series panels or panels from other manufacturers such as Square D, Siemens, or GE. If you're unsure which series your panel is, send us the panel model and we'll confirm.

No — the BR140 is a single-pole (1P) 120V breaker rated at 40A, suitable only for 120V branch circuits. For a 240V circuit you would need a 2-pole BR breaker (such as the BR240). Contact us if you need help selecting the right breaker for your application.
