Description
Engineered for high-density residential power distribution, this 4-pole triplex breaker combines a 30A double-pole circuit with two 20A single-pole circuits. The efficient design frees up valuable room by fitting three circuits into a two-pole space. This plug-on device is compatible with standard Siemens load centers and replaces discontinued MP22030CT breakers. Rated for 10kAIC at 120/240VAC, it includes HACR certification and a common trip function for the center 30A poles.
