Square D QOU130 30A 240V 1-pole Miniature Circuit Breaker

Product Description

The SQUARE D QOU130 is a single-pole miniature circuit breaker rated at 30 amps and 240 volts AC, designed for panel mount installation in residential and light commercial electrical distribution equipment. It provides overcurrent and short-circuit protection for branch circuits serving high-draw loads. The QOU130 accepts 14-2 AWG wire via box lug terminals, making termination straightforward in standard load centers. This breaker meets CSA, IEC, UL, and RoHS standards, confirming suitability across a range of North American and international installation requirements. Licensed electricians install this breaker as part of panel upgrades, circuit additions, or replacement of a failed protective device.

The QOU130 is commonly installed in residential and light commercial panels to protect branch circuits for air conditioning equipment, refrigeration equipment, and heating systems. Its 30-amp rating covers typical single-pole circuits serving dedicated HVAC and refrigeration loads. The panel mount form factor fits QO-style load centers, and the box lug terminal connection accommodates copper or aluminum conductors within the rated AWG range without requiring special adapters in most standard applications.

Compatibility

Intended for use with air conditioning and refrigeration equipment and heating systems as stated by the manufacturer. Verify load center compatibility with the QOU breaker series before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify absence of voltage before removing or installing any circuit breaker. Confirm the load center is listed for use with QOU-series breakers before proceeding. Do not exceed the breaker's rated amperage or wire gauge range when terminating conductors.
