The ABB CAL18-11B Auxiliary Contact Block is a side-mounted, two-pole accessory for compatible ABB contactors.

The block uses screw-type terminals for control wiring and is intended for standard industrial environments. ABB identifies the CAL18-11B as an additional block used together with a first CAL18-11 block on specified contactors. Before selecting this accessory, confirm the contactor model, mounting position and required auxiliary-contact arrangement against the manufacturer’s documentation.
