200 Amp Contactor

InPower’s 3rd generation of DC Power Contactors are a radical design that incorporates Cool Terminal Technology to run cooler than ever, in a smaller package. And InPower’s Load Logic software can handle the high inrush current demands of large resistive, capacitive, and inductive loads. The SSC3 contactors handle your high-current loads intelligently.

Markets: Work Trucks, Delivery Vehicles, Speciality Vehicles, Emergency Vehicles, Shuttle Buses
