Auxiliary contact HKF1-11 - for MS116 1SAM201901R1001

Auxiliary contact for expanding the functionality of motor starters

This auxiliary contact, designated HKF1-11, is designed to work with motor starters of the MS116, MS132 and MS165 series. It serves to add additional auxiliary contacts – normally open (NO) and normally closed (NC) – allowing for the expansion of the control and signaling system functionality. Front mounting and screw connections ensure convenient installation and reliable connections.

Construction and application

The HKF1-11 contact is mounted directly on the front of the motor starter, minimizing the space occupied and simplifying wiring. Its design allows for easy connection of wires using screws, which is particularly appreciated by installers. The presence of both NO and NC contacts provides flexibility in configuring control circuits – it can be used to signal the status of the starter, control other devices, or create safety interlocks.

Mainly used in industrial applications where reliability and the ability to expand motor control functions are required. Thanks to its compact dimensions (45 mm width, 12.5 mm height and 26.5 mm depth), it is ideal for use in switchboards with limited space.
