Application
The 14CUD32AD is well suited for HVAC equipment including air handling units, chiller pumps, cooling tower fans, and other three-phase motor-driven systems operating on 200–208V power. The solid state overload provides precise thermal modeling for improved motor protection compared to traditional bimetallic overloads, reducing nuisance trips while guarding against sustained overload conditions. The open enclosure design makes it straightforward to mount within existing electrical panels or custom motor control centers.
