The CAL5-11 Auxiliary Contact Block from ABB (part number 1SBN010020R1011) is a side-mounted signaling accessory for ABB A-Line contactors (A9–A75), adding an extra pair of contacts without interrupting the main current path. It provides one normally open and one normally closed auxiliary contact, expanding control and feedback options in motor control circuits. Rated for use with control circuits up to 690 VAC and 250 VDC, the CAL5-11 complements ABB’s front- and side-mounted accessories for compact, reliable control deployments.
