Product Description

The Square D QO130CP is a 30-amp, single-pole circuit breaker rated for 120-volt residential and light commercial electrical panels. It is designed for branch circuit overcurrent protection, interrupting the circuit when current exceeds rated capacity to protect wiring and connected loads from damage. The QO130CP occupies 1 space per pole in compatible load centers and ships in bulk packaging. Licensed electricians install this breaker during new construction, panel upgrades, or branch circuit additions in compliance with applicable NEC requirements.

This breaker is suited for residential and light commercial applications where a single-pole, 30-amp branch circuit is required. Common uses include dedicated circuits for electric dryers, water heaters, air handlers, and similar 120-volt loads. It is sold in bulk quantity packaging of 10 units per package, making it a practical choice for contractors stocking panels or completing multiple circuits on a single job.
