ABB Auxiliary Contact 4 Contact 1 NO/3 NC Front Mount 6 A 600 V dc 690 V ac CA4-13M

ABB CA4-13M Auxiliary Contact features a 4-pole design with 1 normally open (NO) and 3 normally closed (NC) contacts. Intended for use in industrial control panels and automation equipment, this front-mounted component provides instantaneous signalling and auxiliary switching for compatible AF series contactors.

Designed for operational currents of 6 A at voltages up to 690 V ac and 600 V dc, it meets industrial safety and endurance requirements with a mechanical durability of 10 million cycles. Screw terminals enhance connection reliability and accommodate a wide range of conductor sizes including ferrules.

Its robust construction supports an operating temperature range from -40°C to 70°C, making it suitable for harsh industrial environments. The auxiliary contact also complies with UL, CSA, NEMA, and IEC standards ensuring quality and safety compliance.

Typical applications include motor control panels requiring status indication, automation racks needing compact front-side auxiliary switching, interlock circuits, and retrofit signalling to existing contactor assemblies. It supports rapid switching frequencies and short-time withstand currents essential to industrial automation systems.

1 NO / 3 NC contact arrangement allows diverse control logic integration. 6 A rated current at 690 V rated insulation voltage ensures compatibility and safety. Front mount installation with screw terminations provides secure, flexible wiring options.

High mechanical endurance reduces maintenance costs through extended operational life. Wide temperature range supports use in challenging environmental conditions. Conforms to major international safety and performance standards.

IP20 protection rating for auxiliary terminals safeguards against accidental contact. Compact packaging facilitates easy inventory management and transport.

This Auxiliary Contact is a reliable component for expanding control capabilities in industrial automation, specifically designed for integration with ABB AF series contactors. It is essential for enhancing control panel signalling and feedback within manufacturing, electrical automation, HVAC, and commercial equipment control systems.
