ABB EH 32C-22 Contactor

The ABB EH 32C-22 Contactor is a rugged, three‑pole, three‑phase motor‑contactor designed to switch heavy industrial loads. Rated for up to 55 A and up to 600 VAC, it is capable of starting and stopping motors up to roughly 30 HP, making it a common choice for conveyors, pumps, fans, and machine tools in industrial control panels. This legacy ASEA design is now supplied by ABB and belongs to the EH family, known for robust operation in demanding environments and compatibility with standard overload protection and interlocking accessories. The coil options cover 110 V at 50/60 Hz and 120 V at 60 Hz, allowing integration with typical control circuits without rewiring; this dual‑voltage coil arrangement matches common North American and international power systems. With three main power contacts and a 600 VAC switching capability, the EH 32C-22 provides reliable, high‑current control for three‑phase loads while maintaining compact form for space‑constrained panels. It is widely used in legacy ABB/ESEA installations and remains a practical choice when upgrading or maintaining older equipment that relies on EH contactors, providing a straightforward plug‑in replacement path when matched to the same coil voltage and electrical rating.
