Description
Engineered for industrial motor control applications, this 50A magnetic-only unit provides instantaneous short-circuit protection. The E-frame design coordinates seamlessly with external motor starters and overload relays. It mounts into legacy ITE and Siemens FC, FCI, and CDP panelboards. For modern upgrades, this specific unit is replaced by the ED63A050, making it an ideal exact-fit solution for older infrastructure. Featuring an adjustable magnetic trip, it allows precise tuning to loads.
