ABB CA4 Series Auxiliary Contact, 6A Contact Current, 690V Contact Voltage - 1SBN010140R1031 CA4-31E


This auxiliary contact provides additional switching logic when fitted to compatible contactors and mounts to the front side for convenient access in control panels. It integrates instantaneous auxiliary contacts with screw terminals and is designed for standard industrial environments where compact, front-mounted signalling or interlocking is required.

Features & Benefits


• 3NO and 1NC instantaneous contacts offering versatile signalling
• 6A operational current for switching control circuits at rated voltages
• 690V rated insulation supporting higher-voltage auxiliary circuits
• Mechanical endurance of 10M cycles for long service life
• Operates from −40°C to 70°C for wide environmental tolerance
• Screw Terminal connections for secure conductor termination

**Applications**


• Suitable for expansion of AF09–AF96 contactor control circuits
• Used for status feedback to PLCs and control relays
• Ideal for interlocking contactor arrangements in motor control
• Used with AFC and AF series contactors for retrofit replacements
• Suitable for factory automation panel signalling functions

How is the unit mounted for retrofits into existing contactor assemblies?


It attaches to the front face of compatible contactors, matching Terminal arrangements for the AF and AFC families to enable straightforward replacement without panel rework.

What conductor sizes can be terminated reliably at the terminals?


Connecting capacity accommodates rigid and flexible conductors from 1 x 0.75 mm² up to 2.5 mm² and insulated ferrules as specified for secure clamping.

What electrical stress ratings apply for impulse and short-time withstand?


The device has a rated impulse withstand voltage of 6 kV and specified short-time withstand currents for brief fault conditions as per auxiliary circuit ratings.

How does switching frequency affect suitability for high-cycle applications?


Maximum electrical switching frequency supports up to several hundred cycles per hour depending on AC/DC duty, while mechanical switching capability reaches many thousands of cycles to match intensive use.
