ABB CAL19-11 Auxiliary Contact Block, 1NO+1NC, Front Mount, Screw Terminals 1SFN010820R1011

Contactors often need additional signaling or interlocking contacts beyond their built-in auxiliary contacts. The ABB CAL19-11 auxiliary contact block solves this by adding one normally open (NO) and one normally closed (NC) contact to ABB AF and NF series contactors, enabling reliable control and status feedback in industrial control circuits.

Who is it for

This auxiliary contact block is intended for panel builders, machine builders, and maintenance technicians who need to expand the functionality of ABB contactors in motor control, automation, and power distribution applications.
