Product Description P/N: QO3020
Description
The Square D QO3020 is a tandem mini molded case circuit breaker designed for branch circuit protection in 120/240VAC systems. It combines two independent single-pole breakers rated at 30 Amps and 20 Amps within one compact plug-in unit. The QO3020 uses a thermal-magnetic trip mechanism to provide reliable overload and short-circuit protection.

Information About QO3020
The QO3020 is part of the Square D QO series, a widely used family of miniature circuit breakers engineered for residential and light commercial distribution systems. Its tandem construction allows two circuits to occupy a single panel space, optimizing load center capacity without compromising protection. The breaker incorporates a trip-free, over-center toggle mechanism and molded case design to ensure consistent interruption performance. It is commonly installed in QO-compatible load centers where space efficiency and dependable branch circuit protection are required.
Key Features:
- Tandem Configuration: Combines two single-pole breakers in one panel space.
- Dual Amp Ratings: Includes one 30A pole and one 20A pole.
- Thermal-Magnetic Trip Unit: Protects against overloads and short circuits.
- VisiTrip Indicator: Provides a visual indication when the breaker has tripped.
- Plug-In Mounting: Enables quick installation in QO load centers.
- 10kA Interrupting Capacity: Rated for standard residential and commercial fault levels.
- HACR Rated: Approved for heating, air conditioning, and refrigeration circuits.
The QO3020 delivers the reliability and precision required for space-efficient residential and light commercial branch circuit protection.
