ABB Series AF Auxiliary Contact, 6A Contact Current, 690V Contact Voltage - 1SBN010140R1240 CA4-40N


This auxiliary contact is a front-mounted, four-pole accessory designed to provide instantaneous switching for industrial control systems. It connects via screw terminals to the front of compatible contactors and is intended for use in standard industrial environments where additional auxiliary signalling or interlocking is required.

Features & Benefits


• 4NO configuration delivers simultaneous signalling across four circuits
• 6A operational current permits control at low to moderate load levels
• 690V insulation rating supports high-voltage auxiliary circuits
• Mechanical endurance 10M cycles ensures long-term operational life
• Operating range −40°C to 70°C maintains function in varied climates
• Screw Terminal mount provides secure, serviceable connections

**Applications**


• Suitable for adding status contacts to control contactors in switchgear cabinets
• Ideal for interlock and signalling circuits in automation panels
• Used with NF and NFC contactor families for matching Terminal layouts
• Can be used for auxiliary switching in motor control centres
• Suitable for retrofit installations requiring front-side mounting

How is the unit secured to a contactor for installation?


It is front-mounted to the contactor and engages mating contactor slots and terminals designed for front-side attachment.

What type of wire and ferrule sizes are compatible with the terminals?


Terminals accept flexible conductors 0.75–2.5 mm² and rigid conductors 1–2.5 mm², with appropriate insulated ferrules for multi-core connections.

What is the expected switching endurance under electrical load?


Mechanical durability is specified at 10M cycles, while electrical switching frequency varies by duty

rated short-time withstand and cycle rates are defined according to application conditions.

Which approvals cover use in regulated installations?


It conforms to international electrical contact standards and holds certifications under IEC, UL and CSA frameworks.
