Square D QHB130 30A 240V 1-pole Bolt-on Circuit Breaker

Product Description

The SQUARE D QHB130 is a single-pole, bolt-on miniature circuit breaker rated for 30 amps at 240 volts AC. It provides overcurrent protection for branch circuits in residential and light commercial electrical panels. The pressure plate terminal connection accepts wire gauges from 14 to 8 AWG, making it compatible with standard copper branch-circuit conductors. The bolt-on mounting style locks the breaker securely to the bus bar, reducing the risk of unintended movement under vibration or thermal cycling. Licensed electricians install this breaker during new construction, panel upgrades, and circuit replacement work.

This breaker is suited for 240-volt single-pole branch circuit applications in load centers and distribution panels where QH-frame bolt-on breakers are specified. Typical installations include dedicated circuits for heating equipment, water heaters, and similar 240-volt single-pole loads in residential or light commercial settings. Its compact form factor fits standard QH-frame panel positions.

Key Features

• 30-amp continuous current rating at 240 volts AC
• Single-pole configuration for 240-volt branch circuits
• Bolt-on mount secures breaker firmly to panel bus bar
• Pressure plate terminal accepts 14 to 8 AWG conductors
• Miniature circuit breaker form factor for space-efficient panel installations

Compatibility

Designed as an OEM-style replacement bolt-on miniature circuit breaker for load centers and distribution panels that accept QH-frame bolt-on breakers.

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 and lock out the panel before removing or installing any circuit breaker. Verify that conductor wire gauge and insulation rating are appropriate for the circuit load before terminating under the pressure plate. Do not exceed the breaker amp rating with connected load.
