Auxiliary contact CA4-10 1SBN010110R1010

Auxiliary contact CA4-10 – a reliable automation component

The CA4-10 auxiliary contact is a compact contact block designed for front mounting in control and signaling circuits. Manufactured by ABB, this device is widely used in industrial installations, providing reliable operation and easy integration with existing systems. It is particularly useful for installers who need a simple but effective solution to expand the functionality of contactors and relays.

Construction and mounting

The CA4-10 is characterized by a solid construction and easy front mounting. Electrical connections are made using screw terminals, ensuring a secure and durable connection of wires with a cross-section of 0.5 to 2.5 mm². Compact dimensions (9.9 mm wide, 43 mm high and 39.5 mm deep) allow installation in tight spaces. Top mounting also facilitates access and configuration.

Application and benefits

This auxiliary contact has one normally open contact (1NO), which means it is ideal for simple signaling or control applications. The rated operating current of 4A at 230V AC (AC-15) ensures compatibility with most standard control circuits. Thanks to compliance with IEC 60947-5-1 standards, the device guarantees safety and reliability of operation. It allows expanding the functionality of contactors of the AF09…AF96 and NF(C)(Z)(B) series, making it a versatile element of every electrical workshop equipment.

• Simple mounting: Front mounting with screw terminals facilitates quick installation and connection of wires.
• Compact dimensions: Allow installation in limited space without the need to modify existing infrastructure.
• Reliability: Compliance with IEC 60947-5-1 standards guarantees safe and stable operation in demanding industrial conditions.
• Versatility: Ideal for signaling and control applications in combination with AF series contactors and relays.
• Durable connections: Screw connections ensure a secure connection of wires with a cross-section of 0.5-2.5 mm².
• Wide voltage range: Operation in the range of auxiliary circuit voltage 24–690 V AC provides flexibility in use in various systems.

Thanks to its construction and technical specifications, the CA4-10 auxiliary contact is an optimal solution for both professional installers looking for a reliable component for their projects, and for end-users who need a simple way to expand the functionality of existing control systems.
