Siemens Q21520CT – 15/20A Triplex Miniature Circuit Breaker New Release

Built for high-density residential applications, the Siemens Q21520CT combines two 1-pole 15A circuits and one 2-pole 20A circuit into a 2-inch module. This helps electricians add branch circuits without upgrading the panelboard. Featuring a CTL rejection clip, it mounts into Siemens EQ, PL, ES, and Ultimate load centers. It also replaces the discontinued MP21520CT. The center poles utilize a common trip mechanism for 240V loads, maintaining a 10kAIC rating at 120/240V.
