Square D QOB230VH Bolt-On Circuit Breaker 30A 240V 2P

The Square D QOB230VH is a bolt-on miniature circuit breaker rated for 30 A at 240 V, configured as a 2-pole device for 120/240 VAC circuits with a 22 kA interrupting rating. Bolt-on mounting provides a secure mechanical fit to compatible Square D QO load centers, and the unit uses thermal-magnetic overcurrent protection to trip on overloads or short circuits, helping protect conductors and connected equipment. The model number QOB230VH is documented as a 30 A, 2-pole, 120/240 VAC breaker with a 22 kA short-circuit rating at 240 VAC, a specification verified by Schneider Electric and distributor datasheets. As a bolt-on option in the QO/QOB family, it offers a straightforward replacement path for panels that require a bolt-on 2-pole protection device in 120/240 VAC distributions.
