ABB 1SBN010140R1231

The CA4-31N auxiliary contact block is engineered for front mounting and provides a total of 4 poles with 3 normally open (N.O.) and 1 normally closed (N.C.) instantaneous contacts. This configuration aligns with the requirements of the NF(C)(Z)(B) contactor relays, making it ideal for various industrial environments.

With a compact design, the block measures 43 mm in width, 39.5 mm in depth, and 43 mm in height, weighing only 0.055 kg. It supports a range of wire sizes for connections, accommodating flexible and rigid stranded conductors with a capacity of 0.75 to 2.5 mm². The maximum electrical switching frequency is rated at 1200 cycles per hour for AC-15 and 900 cycles per hour for DC-13, providing versatile operation in demanding conditions.

This product adheres to multiple standards including IEC 60947-5-1 and UL 60947-5-1, ensuring compatibility and safety across various applications. The rated operational voltage reaches up to 690 V, with a conventional free-air thermal current of 16 A at 40 °C, allowing for reliable performance in a wide range of operational scenarios.

For secure mounting, the block utilizes screw terminals and requires a tightening torque of 1.2 N·m, while the wire stripping length is specified at 10 mm, facilitating straightforward installation.
