IEC overload relays provide reliable and accurate electronic or thermal protection from device or component overload or phase loss. Units from Eaton, Fuji Electric, Schneider Electric, WEG Electric, AutomationDirect, and Ironhorse are available in a range of amperage capacities. Select models offer configurable parameters, self-powered operation, and communications capabilities.
Worldwide Electric definite purpose contactors are designed for application-specific use, such as HVAC or compressors, providing reliable load control that can handle diverse switching needs. These compact contactors are available in up to 60A capacities, in 1- or 3-phase configurations, and with coil voltages from 120 to 480 VAC.
Manual motor controllers and disconnects safely control and disconnect power from motors. UL 508 rated open frame and enclosed devices are available from reliable brands including Bryant, Merz, and Socomec.
Pin and sleeve interlocked motor disconnects provide convenient and safe connection for mobile equipment.
ProSense motor control relays perform protective functions for motors and components to ensure proper and efficient operation.
