The QBH140 Eaton 1P 40A 120V Bolt On Breaker is designed for reliable circuit protection in residential and commercial applications. This single-pole breaker boasts a quick-install design and exceptional durability, ensuring optimal performance and safety. Ideal for various electrical needs, it offers a dependable solution for your power distribution requirements.
The QBH series uses a bolt-on bus connection, while standard Eaton CH breakers use a plug-in (snap-in) bus connection. These two mounting styles are not interchangeable. You can only install the QBH140 in a panelboard that is specifically designed to accept bolt-on breakers. Check your panel's label or send us the model number and we'll confirm compatibility before you order.

A 10 kA interrupting rating meets the available fault current in most Canadian residential services and many light-commercial branch circuits. However, you should always verify the available short-circuit current at the point of installation — typically found on your utility or engineering documents. If your panel requires a higher AIC rating, we can help identify a suitable alternative. An electrician or engineer can confirm what's required for your specific installation under the Canadian Electrical Code (CEC).
