Description
Built for heavy-duty motor control, the Siemens EF3H150 is a 150A, 3-pole magnetic-only circuit protector. It delivers instantaneous trip response to defend industrial motor branch circuits from damaging short circuits. The bolt-on E-frame unit installs into legacy Siemens and I-T-E panelboards. While it has been replaced by the FXD63A150, transitioning to the newer substitute requires specific panel modifications. Operating at up to 600VAC, this device includes a 14kAIC rating at 480V.
