The Eaton QBH120 is a bolt-on style breaker from Eaton's QBH series, designed to mount securely in compatible Eaton bolt-on panelboards and loadcentres. As a 1-pole, 20A, 120V breaker with a 10kA interrupt rating, it is suitable for both residential and light commercial panel applications that accept the QBH bolt-on frame.
Bolt-on breakers are not interchangeable with plug-in style breakers — confirm your panel accepts the QBH bolt-on type before ordering. Send us your panel model number and we'll confirm fitment for you.
The QBH120 uses a bolt-on mounting design, meaning it fastens mechanically to the panelboard bus bar with a bolt rather than clipping on. This provides a more secure connection and is required by certain panel designs — particularly in commercial applications. It is not interchangeable with plug-in style breakers, so always verify your panel type before purchasing.
The QBH series can be difficult to source through standard supply channels, especially in older or legacy panel configurations. Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain Canadian stock at our Calgary, Edmonton, and Vancouver counters. Contact us for current availability — we're happy to help locate the right breaker for your project.
Yes, provided your existing panelboard accepts Eaton QBH bolt-on breakers and the 20A, 1-pole, 120V rating matches your circuit requirements. Always ensure the panel's bus bar design is compatible with the QBH bolt-on frame. If you're unsure, share your panel model with us and our team will confirm the correct replacement.
