Square D QOB330VH 3-pole Bolt-on Circuit Breaker 30A

Product Description

The SQUARE D QOB330VH is a 3-pole, bolt-on miniature circuit breaker rated for 30 amps at 240 volts AC. It provides overcurrent and short-circuit protection in three-phase and multi-wire branch circuit applications. The pressure plate terminal connection accepts 14 to 8 AWG wire, making it suitable for a range of commercial and light industrial load circuits. Licensed electricians install this breaker during panel work, service upgrades, or branch circuit additions. It carries UL Listed and CSA certifications and meets RoHS compliance requirements, confirming it meets recognized North American safety standards.

The QOB330VH is designed for use with Square D NQOD panelboards. It is appropriate for commercial electrical distribution systems where bolt-on breakers are specified for vibration resistance and secure termination. Typical applications include multi-wire branch circuits, HVAC equipment disconnects, and light commercial panel installations requiring a 3-pole overcurrent device in a bolt-on configuration.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify the absence of voltage before installing or replacing any circuit breaker. Confirm the panelboard is rated for bolt-on breakers and that conductor sizing matches the 14 to 8 AWG terminal range. Do not install this breaker in a panel for which it is not listed or approved.
