The QBH270 – EATON 2P70A 240V Bolt On Breaker is a reliable and efficient solution for your electrical needs. Designed for durability, this two-pole breaker offers a 70-amp capacity, ensuring optimal performance in demanding applications. Ideal for residential and commercial use, it easily integrates into existing systems for enhanced safety and reliability.
The QBH270 is a bolt-on style breaker from Eaton's QBH series, generally compatible with Eaton/Cutler-Hammer CH-type panelboards that accept bolt-on breakers. It is not a plug-in style and will not fit plug-in-only loadcentres. If you're unsure about your panel, send us the model number and we'll confirm the fit.
In many cases, yes — the QBH series is a current Eaton offering that can serve as a direct or cross-reference replacement for compatible legacy Eaton and Cutler-Hammer bolt-on breakers of the same rating (2P, 70A, 240V, 10kA). However, always verify the replacement matches the original breaker's style (bolt-on vs. plug-in), pole count, amperage, and panel compatibility before installing. Contact our team if you need help cross-referencing an older part number.
A 10,000 AIC (ampere interrupting capacity) rating is standard for many residential and light-commercial applications in Canada. However, you must confirm that the available fault current at your panel does not exceed 10kA. For installations closer to the utility transformer or in commercial settings with higher fault currents, a higher-AIC breaker may be required. Consult a licensed electrician or contact us if you need guidance on selecting the right interrupting rating.
