The QBHW3050H by EATON is a robust 3-pole, 50A bolt-on circuit breaker designed for 240V applications, providing reliable protection with a 22kA interrupting capacity. Ideal for both residential and commercial use, this breaker ensures safe operation and peace of mind. Trust EATON for dependable power management solutions.
The QBHW3050H uses a bolt-on mounting style, which is typically found in Eaton/Cutler-Hammer commercial panelboards that are designed to accept bolt-on breakers. It is not compatible with standard residential loadcentres that use plug-on (clip-in) breakers like the BR or CH series. If you're unsure whether your panelboard accepts bolt-on breakers, send us your panel model number and we'll confirm.
No — the QBHW series uses a bolt-on mounting and is not interchangeable with Eaton's plug-on CH or BR series breakers. While all three are Eaton products, the mounting style and bus compatibility differ. Always verify the replacement matches your panel's required breaker type before ordering. Contact our team and we can help match the right breaker to your application.
The QBHW3050H carries a 22kA interrupting rating at 240V, which meets the requirements of many commercial and light-industrial applications in Canada. However, available fault current at your panel must be calculated or verified by a licensed electrician to ensure it does not exceed 22kA — as required by the Canadian Electrical Code (CEC). If your service has higher available fault current, a higher-rated breaker would be required.
