Product Description

ABB CA4-40U Auxiliary Contact is a high-quality industrial component providing four normally open (4 NO) contacts designed to be mounted at the front side of compatible contactors. It operates with a rated current of 6 A and can handle contact voltages of 600 V DC and 690 V AC, making it ideal for varied industrial control circuits and signalling applications.

Engineered for durability, this unit delivers up to 10 million mechanical cycles, supporting reliability and long-term use in automation environments. Its robust construction withstands temperatures from -40°C to 70°C, suitable for harsh and fluctuating industrial conditions.

The front-mount configuration facilitates simple installation on contactor faces with secure screw terminal connections that accept flexible and rigid conductors, accommodating single conductors in the range 0.75 - 2.5 mm² and dual insulated ferrules up to 1.5 mm². This ensures compatibility with common wiring practices in control panels.

Applications include motor starter status signalling, interlock functions, control circuit indication, and safety feedback in diverse manufacturing and automation systems. Its capability to withstand short-time fault currents, with ratings of 140 A for 0.1 seconds and 100 A for 1 second in AC-15 switching duty, assures robustness under short-duration electrical stresses.

The device complies with recognized safety standards UL 508 and CSA C22.2 N14, reinforcing its suitability for industrial control gear applications. Mounting and compatibility are assured for certain 3-pole contactor frames, providing correct mechanical fit and alignment.

Four normally open instantaneous contacts for control and signalling. Rated for 6 A contact current compatible with low-power control circuits. Voltage ratings of 600 V DC and 690 V AC for versatile use. Front mounting with screw terminal connections for easy installation.

Mechanical durability rated for 10 million cycles. Operating temperature range from -40°C to 70°C. Supports motor starter status signalling and interlocks. Accepts conductor ranges for flexible and rigid wiring standards.

Complies with UL 508 and CSA C22.2 N14 standards.
