The ABB 1SAM201902R1001, also known as the HK1-11, is a front-mounted auxiliary contact block designed for use with ABB’s MS116, MS132, and MS165 series of manual motor starters. This compact and reliable accessory enhances the functionality of your motor protection setup by providing additional signaling contacts. It features one normally open (NO) and one normally closed (NC) contact, allowing for remote status indication or integration into a larger control circuit. Installation is simple and tool-free, as the block snaps directly onto the front of the motor starter, saving valuable time and panel space.
