The ABB HKF1-11 Auxiliary Contact Motor Controller is a quick connect component used with motor protection switches and manual motor starters in HVAC systems. It attaches to compatible switching equipment to provide additional signaling contacts that mirror the main contact position. It allows external monitoring, interlocking, or status indication in control circuits. It is mounted directly onto the side or front of the main equipment and operates mechanically with its switching action. It is used in industrial control panels. It supports expanded control logic, safety input, and system coordination in motor control applications.
