ABB CAL16-11C Auxiliary Contact Block adds one normally open and one normally closed contact to ABB four-pole reversing contactors with VH800 interlocks, mounted on the side of the main unit. This side-mount accessory (SK829002-C) features screw-terminal connections and is rated for up to 10 A at 600 V AC, designed for use with ABB EK550/EK1000 family contactors in motor-control and power-distribution applications. It expands signaling and interlock options for control circuits without altering the main contactor performance.
