1SAM201901R1002

ABB 1SAM201901R1002 HKF1-20 Auxiliary Contact is a front-mounted auxiliary contact block designed for ABB manual motor starters and motor protection applications. It features a 2NO (two normally open) contact configuration and changes switching position together with the main contacts of the manual motor starter.

The HKF1-20 provides additional signaling and control contacts for applications such as motor status indication, electrical interlocking, PLC signaling, control circuits and industrial automation panels. It mounts directly on the front of compatible ABB MS116, MS132 and MS165 manual motor starters, helping maintain a compact installation inside control panels and motor control centers. ABB specifies screw-terminal connections, a 250 V rated insulation voltage, and an operating temperature range of -25°C to +60°C.
