Industrial BBI EHCK175-3 N Circuit Breaker Unit

The ABB EHCK175-3 N is a three-pole replacement contact kit (P/N EHCK175-3) designed for ABB EH175 series contactors, providing OEM-grade components to restore the switching performance of three-phase motor-control circuits when the original contacts are worn or damaged. As an official ABB replacement part, EHCK175-3 N is compatible with ABB EH175 contactors and is cross-referenced as a replacement for KZ175-3, enabling straightforward integration with legacy ABB/CAD motor-control assemblies. Listings from ABB and distributors describe EHCK175-3 as a 3-pole contact kit for EH175 and related KZ175 devices, confirming its role as a genuine OEM accessory rather than a standalone circuit breaker. Use EHCK175-3 N in service or upgrade projects on ABB EH175-based control panels where a replacement contact kit is required to maintain reliable three-phase switching for equipment such as conveyors, pumps, and fans that rely on ABB motor controllers.
