ABB 1sam201902r1001 Auxiliary Contact Assembly

ABB 1SAM201902R1001 HK1-11 Auxiliary Contact Assembly is a right-hand side mounted auxiliary contact block for ABB MS-series manual motor starters. It provides a 1NO + 1NC contact configuration (one normally open, one normally closed) with screw-terminal leads, designed to switch control circuits in concert with the starter’s main contacts. As the main contacts move, the auxiliary contacts change state in tandem, enabling reliable feedback signals for automation and interlock logic. The block is rated for up to 6 A at 690 VAC and up to 600 VDC, with an impulse withstand rating of 6 kV, making it suitable for moderate-power control environments. Suitable for use with ABB MS-series starters such as MS116, MS/MO132, and MS/MO165, the HK1-11 is an add-on that preserves available poles while expanding signaling options. Its compact form and right-side mounting keep wiring and panel layout clean, and the screw-terminal connection supports secure, vibration-resistant terminations in industrial panels.
