ABB Auxiliary Contact Block, 4 Contact, 2 NC/2 NO, CA4-22N, Front, 6 A, 690V, 1SBN010140R1222

This auxiliary contact Block provides additional switching contacts to complement a contactor, enabling auxiliary signalling and interlock functions in control panels and automation systems. It is designed for front mounting and integrates with devices requiring a compact, front-mounted contact solution, offering rated insulation for higher-voltage installations.

• Four-pole configuration offers expanded control and signalling capability
• 2NC/2NO arrangement supports both break and make signalling functions
• Rated operational current 6 A enables moderate control circuit loads
• Insulation rating 690V suits elevated voltage applications
• Screw terminals permit secure, tool-tightened conductor connections
• Mechanical life 3,600 cycles ensures repeatable service in switching sequences

• Suitable for retrofitting auxiliary contacts on contactors in motor control centres
• Ideal for status feedback in PLC-based automation cabinets
• Used for interlock circuits in industrial machinery control panels
• Can be used for pilot signalling in distribution switchgear assemblies

It attaches at the front of the primary device, aligning with front-mount interfaces for straightforward installation without rear access.

It has been assessed to standards recognised by CSA and UL for component-level performance and compatibility.

Connections are via screw-type terminals that accommodate standard control conductors and enable firm clamping.

There are four contacts in a 4-pole layout arranged as two normally closed and two normally open elements to cover diverse signalling needs.
