1SAM201902R1001

ABB 1SAM201902R1001 HK1-11 Auxiliary Contact is a side-mounted auxiliary contact block designed for ABB manual motor starters and motor protection applications. It provides one normally open (1NO) and one normally closed (1NC) auxiliary contact, enabling reliable status signaling, electrical interlocking, PLC feedback and control-circuit functions. The HK1-11 is mounted laterally on compatible ABB manual motor starters such as the MS116 and MS132. Its compact design is suited to industrial control panels, motor control centers, machinery panels and automation systems where additional signaling contacts are required. The accessory uses screw terminals, has a rated insulation voltage of 690 V, and ABB specifies an operating temperature range of -25°C to +60°C.
