Description
Designed specifically for motor branch circuits, the Siemens EF3A025 is a 3-pole magnetic-only protector. It provides essential instantaneous trip functions to prevent damage during short-circuit events. The 25A bolt-on device is compatible with legacy I-T-E and Siemens FC-1 panelboards as well as FC-20 switchboards. Users looking for a modern equivalent can use the ED63A025 replacement. With an adjustable magnetic range of 75-210A, it allows precise alignment with motor overload relays.
