Square D QOB230H 2 Pole Bolt-on Circuit Breaker 30A 240V

Product Description

The SQUARE D QOB230H is a 2-pole, bolt-on miniature circuit breaker rated for 30 amps at 240 volts AC. It provides overcurrent and short-circuit protection for branch circuits in residential and light commercial electrical panels. The bolt-on terminal design secures the breaker directly to the bus bar, and pressure plate terminals accept 14 to 8 AWG conductors. Licensed electricians install this breaker as a direct panel replacement or in new circuit applications where a bolt-on style breaker is required.

This circuit breaker is suited for 240-volt branch circuits such as HVAC equipment feeds, water heaters, dryers, and similar double-pole loads. Its compact miniature form factor fits panelboards designed to accept bolt-on style breakers. The 30-amp rating covers a broad range of residential and light commercial branch circuit applications where a 2-pole overcurrent device is required by code.

Key Features

• 30-amp continuous current rating for 240-volt, 2-pole branch circuits
• Bolt-on mounting style secures directly to panelboard bus bar
• Pressure plate terminal connection accepts 14 to 8 AWG wire
• Miniature form factor for space-efficient panel installation

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 handling or installing the breaker. Confirm the panelboard is rated for bolt-on style breakers before installation. Do not exceed the conductor size range specified for the pressure plate terminals.
