The QBH150 – EATON 1P150A 120V Bolt-On Breaker is designed for reliable circuit protection in residential and commercial applications. This high-performance breaker features a 150 Amp rating and single-pole configuration, ensuring optimal safety and efficiency. Ideal for use in various electrical systems, it delivers dependable performance when you need it most.
A bolt-on breaker like the QBH150 is mechanically secured to the busbar with a screw, providing a more rigid connection — common in Eaton CH-style panelboards designed for bolt-on breakers. Plug-in breakers simply clip onto the bus. The two styles are not interchangeable, so it's important to verify your panel accepts bolt-on QBH-frame breakers before ordering. Send us your panel model and we'll confirm compatibility.
A 10kA interrupting rating is standard for many residential and light commercial services in Canada. However, if your service panel is fed by a larger utility transformer or your available fault current exceeds 10kA, you would need a higher-AIC rated breaker. Your licensed electrician or a short-circuit study can determine the available fault current at your panel. Contact our team if you need help selecting the right AIC rating.
Northern Breaker Group specializes in obsolete and hard-to-find breakers, including Eaton QBH-frame units. Stock levels vary, but we actively source legacy and current-production Eaton breakers across our Calgary, Edmonton, and Vancouver locations. Contact us for availability and we'll provide a quote — often for breakers other suppliers can't locate.
