ABB CA5-10 Auxiliary Contact

The ABB CA5-10 Auxiliary Contact is a high-performance, single-pole front-mounted contact block engineered to expand the control and signaling functions of A-series contactors and N-series contactor relays. This vertical front face auxiliary contact features one normally open (NO) configuration, providing reliable instantaneous feedback for industrial automation logic and safety interlocking systems. Designed for demanding HVACR and industrial applications, it integrates seamlessly with A9 to A75 contactors, offering a compact footprint that does not increase the lateral space required in electrical panels. Equipped with high-conductivity screw terminals, the CA5-10 ensures secure wiring and maintains consistent performance across a rated operational voltage of up to 690V AC. With a mechanical durability of 10 million cycles and a degree of protection rated at IP20, this ABB contactor accessory is built for longevity in standard industrial environments. Its snap-on installation allows for rapid field upgrades, minimizing downtime during maintenance or system expansion.

• Instantaneous 1 NO Logic: Provides immediate status signaling for motor starters and automated control circuits.
• Space-Efficient Front Mounting: Direct attachment to the front of the contactor saves critical DIN rail or panel space.
• Wide Compatibility Range: Fully compatible with ABB A-line contactors from A9 through A75 models.
• Robust Electrical Endurance: Capable of handling up to 1200 electrical switching cycles per hour for high-frequency operations.
• Simplified Integration: Features intuitive screw terminal connections for reliable and straightforward field wiring.

• Can the CA5-10 be used with side-mount accessories? Yes, this front-mounted block is designed to work alongside side-mounted auxiliary contacts on compatible A-series contactors.
• Is this auxiliary contact suitable for DC circuits? Yes, while optimized for AC-15 applications, it is rated for DC-13 operational currents (e.g., 2 A at 240V DC).
• How many CA5-10 blocks can be added to a single contactor? Depending on the specific A-line contactor model, multiple front-mounted auxiliary blocks can be utilized; consult the contactor’s technical data sheet for maximum block capacity.
