ABB HKF1-11K Relay

ABB HKF1-11K is an auxiliary contact block designed for front mounting on ABB HKF1 motor starters. It provides an additional signaling contact that mirrors the main contact's status, enabling feedback to control circuits, interlocks, alarms, or logic in industrial automation panels. The HKF1-11K uses front-mount integration with Push-In terminals, allowing tool-free wiring while preserving a compact, integrated footprint alongside compatible HKF1 family devices. This accessory is intended for use with ABB HKF1 series starters and related front-mount configurations, extending the capability of MS-series motor starters in equipment such as conveyors, pumps, fans, and other industrial drive applications. By adding this auxiliary contact, panel designers can implement simpler interlocks and status indications directly in the starter assembly, helping improve diagnostics and safety interlocks in control schemes. The HKF1-11K leverages ABB's engineering standards to deliver dependable signaling for automation architectures that rely on accurate feedback from motor protection and control equipment. Typical applications include motor control panels, machine automation, and safety interlock circuits where visible or electrical confirmation of the starter's state is required.
