The QBHW3030H Eaton 3P 30A 240V Bolt-On Breaker offers reliable protection and performance for your electrical systems. With a robust 22kA short-circuit rating, this three-pole circuit breaker is designed for superior durability and efficiency. Ideal for commercial and residential applications, it’s the perfect choice for dependable electrical safety.
The QBHW series is Eaton's higher-interrupting-capacity bolt-on line, rated at 22kA compared to the 10kA rating typical of standard CH bolt-on breakers. This makes the QBHW3030H a better choice for installations closer to the service entrance or where fault current levels are higher, such as many commercial applications.
The QBHW3030H is a current Eaton production breaker and may serve as a replacement for compatible legacy Cutler-Hammer or Eaton bolt-on units in CH-type panelboards — provided the panel accepts the QBHW frame and the bus stab configuration matches. Always verify your panel's approved breaker list or send us your panel model and we'll help confirm the correct fit.
Yes — the QBHW3030H is a true 3-pole breaker rated for 240V AC, making it suitable for three-phase 240V systems (e.g., 240V delta) as well as single-phase 240V three-wire applications such as sub-panel feeds or large equipment loads. It is not rated for 208Y/120V or 480V systems, so confirm your system voltage before specifying this breaker.
