Industrial EH300 Three-Phase Contactor 350A 600V 250HP

ABB EH300 is a three‑pole magnetic contactor rated for 350 A at up to 600 V AC, capable of starting and running motors up to 250 HP at 600 V—making it suitable for heavy‑duty motor control in pumps, fans, conveyors, and compressors within industrial facilities. It belongs to ABB's EH series, designed for reliable switching and isolation of three‑phase loads, and many configurations include one normally open and one normally closed auxiliary contact to support signaling and simple interlocks. Coil options for EH300 variants span the 100–250 VAC or DC range, enabling integration with a variety of control circuits. Official data for the EH300 family lists 350 A and 600 V ratings with HP equivalents around 75/200/250 HP depending on voltage, and retailer listings corroborate the 3P, 350 A, 600 V configuration for models such as EH300C‑1L.
