The QBHW2100 is an Eaton 2-Pole 100A 240V Bolt-On Circuit Breaker, designed for reliable performance in residential and commercial applications. With a short-circuit interrupting capacity of 22kA, this breaker provides superior protection for your electrical systems. Ideal for various installations, it ensures safety and compliance with your power needs.
Bolt-on breakers (like the QBHW2100) are mechanically fastened to the bus bar with a screw or clamp, providing a more secure connection — common in commercial panelboards and some residential sub-panels. Plug-in breakers simply snap onto the bus. Your panel's interior label or door directory will indicate which type is required. If you're unsure, send us your panel model and we can confirm.
Yes — a 2-Pole 100A breaker like the QBHW2100 is commonly used as the main disconnect in a 100A residential or light-commercial sub-panel, provided the panelboard is rated for a main breaker of this size and accepts bolt-on type breakers. Always verify the panel's maximum main breaker rating and consult a licensed electrician to ensure compliance with local Canadian Electrical Code requirements.
