Description

Built for industrial motor control applications, the EF3A005 is a 3-pole, 5A motor circuit protector featuring an adjustable magnetic-only trip mechanism. It operates at up to 600VAC and 250VDC, delivering 14kAIC at 480V for robust short-circuit protection. Designed to mount into Siemens motor control centers and legacy I-T-E FC-1 panelboards, it requires coordination with a separate overload relay. This E-frame unit replaces older installations and is superseded by the ED63A005.
