Siemens Q2020 Duplex Circuit Breaker, 20a/20a, 1-pole, 120/240v

The Siemens Q2020 Duplex Circuit Breaker is a complete, unenclosed molded-case breaker designed to provide reliable electrical protection in residential and light-commercial applications. This innovative duplex design replaces two single-pole breakers while occupying just one inch of panel space, making it an ideal solution for maximizing panel capacity and simplifying circuit layouts without sacrificing safety or performance.

By combining two independent 20-amp circuits in a single compact housing, this breaker delivers separate control for parallel loads such as kitchen appliances, HVAC units, and other high-demand equipment. The space-saving design allows electricians and homeowners to add more circuits to existing panels without expanding the enclosure, while the fixed-trip mechanism ensures consistent, reliable protection against overloads and short circuits.

Features and Benefits

• Dual Independent Poles: Two separate 20-amp breakers share a common housing, providing independent control for two circuits while using the footprint of a single-pole breaker.
• Space-Saving Design: Takes the place of two single-pole breakers in just one inch of panel space, enabling additional circuits without expanding the enclosure.
• Quick Installation: Plug-mounting design allows fast insertion without removing the panel cover, reducing installation time.
• High Interrupt Rating: 10,000 AIR provides strong protection against fault currents and short circuits.
• Broad Compatibility: Will replace breakers from American Switch, Westinghouse Type BR, Bryant, Challenger, Sylvania, Crouse-Hinds, Murray, Frank Adams, General Electric (full size only), General Switch, I-T-E, Gould, Montgomery Ward, and Sears panels.
• Dual Ratings: HACR and SWD rated for heating, air-conditioning, and motor applications as well as switch duty operations.
