Product Description
ABB CA4-31M Auxiliary Contact is a robust 4-contact front-mounted block designed to expand control circuits in industrial environments. This unit comprises 3 normally open (NO) and 1 normally closed (NC) instantaneous contacts to provide reliable monitoring or signaling of contactor status. It is engineered for mounting on the front side of compatible contactors using screw terminals for secure connections.
The contact supports an operational current of 6 A and can handle contact voltages of up to 600 V dc and 690 V ac, making it suitable for demanding auxiliary circuits. With a rated insulation voltage (Ui) of 690 V, the device ensures electrical safety and performance under high-voltage conditions.
The mechanical durability of this auxiliary contact reaches 10 million cycles, minimizing maintenance and replacement needs in industrial applications. It operates efficiently within a broad temperature range of -40°C to 70°C, suitable for harsh ambient conditions often encountered in manufacturing and automation setups.
This design supports installation simplicity and operational safety.
Common industrial applications include extending auxiliary circuit functionality on AF09 - AF16 contactors, providing status feedback in motor starter panels, integration with control relays for automation interlocks, and lamp or PLC signaling within electrical switchgear systems.
Standards compliance includes UL 508 and CSA C22.2 N14, reflecting its suitability for North American industrial safety and electrical codes. The auxiliary contact’s construction incorporates IP20 basic finger protection rating when installed within typical control enclosures, ensuring operator safety.
This product contains 4 contacts comprised of 3 NO and 1 NC configuration. 6 A contact current ensures effective control for industrial operations. Front mounting with screw terminals for installation flexibility. Rated insulation voltage of 690 V supports high-voltage circuits.
Operates over a wide temperature range from -40°C to 70°C. Explore more products in our Automation & Control Gear category for comprehensive industrial control solutions.
