The 1SAM201902R1001 is an ABB HK1-11 auxiliary contact block designed for use with ABB motor protection and control devices. This accessory provides additional switching contacts that allow the status of connected protection equipment to be transferred to external control circuits, indicators, or monitoring systems.
Unlike primary switching components such as circuit breakers or contactors, the HK1-11 operates as an accessory module installed alongside compatible ABB protection devices. It expands the available contact configuration without changing the main protective function of the connected equipment.
The complete ABB order code 1SAM201902R1001 is used for identification because HK series auxiliary contacts are available with different contact arrangements and mounting configurations.
