Description
Engineered for residential applications, this space-saving QT series component provides two 15A single-pole circuits and one 50A double-pole circuit with a common trip. It mounts into Siemens EQ, PL, ES, and legacy Murray load centers requiring CTL (circuit limiting) configurations. By consolidating multiple circuits into just two standard panel spaces, it offers an efficient solution for expanding capacity without upgrading the entire enclosure. Replaces the discontinued MP21550CT.
