Siemens Q22020CT Triplex Miniature Circuit Breaker

This QT series breaker is designed for installation in Siemens EQ, PL, ES, and Ultimate load centers that are listed to accept tandem or quad breakers. It is also a UL-verified substitute for the Murray MP22020 and MP22020CT2.

This device packs four poles into a two-space footprint. It provides two independent 20A single-pole circuits on the outer positions and one 20A double-pole circuit on the inner positions.

The Q22020CT requires two standard 1-inch panel spaces. It is designed to maximize available slots in residential service equipment by combining three circuits into a compact form factor.

Yes, the inner 20A double-pole configuration includes an internal common trip function for 240V applications. If a fault occurs on either leg of the 240V circuit, both inner poles will trip simultaneously.

Yes, Siemens has issued official documentation verifying the Q22020CT as a direct, code-compliant substitute for the obsolete Murray MP22020 and MP22020CT2 circuit breakers.

Yes, this breaker includes a Circuit Total Limitation (CTL) rejection clip. It is designed to be installed only in load centers with notched bus stabs that are specifically rated to accept tandem or quad breakers.

Yes, this breaker is HACR rated for use with heating, air conditioning, and refrigeration equipment. The 20A single-pole circuits are also SWD (Switching Duty) rated for switching 120V fluorescent lighting loads.
