Product Description

The ABB HKF1-11 is a front-mounted auxiliary contact block designed for use with MS116, MS132, and MS165 manual motor starters. It features a 1 NO (Normally Open) and 1 NC (Normally Closed) contact configuration. This auxiliary switch is essential for indicating the position of the main contacts of the motor starter, allowing for status signaling, electrical interlocking, or control logic integration. Its tool-free, front-mount design ensures quick and easy installation without increasing the width of the starter, making it a space-efficient solution for motor control panels.

Standard Features

  • Status Signaling: Provides real-time feedback of the manual motor starter’s ON/OFF status

  • Electrical Interlocking: Enables safety interlocking between multiple motor control devices

  • Space Saving: Front-mount configuration preserves DIN rail width for more devices

  • Snap-On Installation: Easy mechanical attachment to the front of compatible ABB starters without tools

  • Dual Logic: Simultaneous NO and NC signals allow for flexible control circuit designs

  • High Reliability: Silver-plated contacts ensure low-level signal integrity and long life
