The QOB2100VH is a high-performance Square D 2-Pole 100 Amp Bolt-On Circuit Breaker designed for 120/240V applications. With a robust interrupting capacity of 22kA, it ensures reliable protection for your electrical systems. Ideal for residential or commercial use, this breaker provides peace of mind and safety in power distribution.
The key difference is the mounting style. The QOB2100VH is a bolt-on breaker, meaning it bolts directly to the bus bar of a compatible QO panelboard. A standard QO breaker uses a plug-on connection. Bolt-on breakers are typically specified for commercial panelboards where a more secure, vibration-resistant connection is required. They are not interchangeable — always verify your panelboard accepts bolt-on breakers before ordering.
The QOB2100VH can be used as a feeder or sub-feed breaker in a compatible QO bolt-on panelboard, and may also serve as a main breaker depending on the panelboard's design and configuration. Its 100A, 2-Pole, 22kA rating makes it well suited for feeder applications in both residential service entrance and commercial distribution scenarios. Consult your panelboard's documentation or contact us to confirm the intended application.
