Miniature auxiliary contactor, TeSys K, 2NO 2NC, 24VDC coil, spring terminals CA3KN313BD3

Auxiliary contactor – reliable control in your installation

This miniature auxiliary contactor from the TeSys K series is a key element in control systems, designed for reliable operation with electromagnetic loads. It is ideally suited for both professional and home installations where high functionality and safety are required. Equipped with a 24VDC coil and spring terminals, it provides quick and easy installation and convenient connection of wires.

Design and application

This contactor is designed to control AC-15 and DC-13 circuits. Its compact dimensions (width 45 mm) allow for installation in tight spaces, and the possibility of installation on a 35 mm DIN rail or with screws provides flexibility during installation. The use of spring terminals significantly reduces the time it takes to connect wires, which is particularly important when implementing larger projects. The contactor design guarantees a high operating frequency – up to 180 cycles per minute – and stable operation over a wide temperature range (from -25°C to +50°C).

Key features and benefits

• Versatility: Thanks to the 2NO (normally open) and 2NC (normally closed) contact configuration, the contactor can be used in a variety of control applications.
• Easy installation: Spring terminals allow for quick and easy connection of wires without the need for tools.
• Compact dimensions: A width of only 45 mm allows the contactor to be installed even in limited space.
• High reliability: Made of high-quality materials and compliant with many standards (IEC, UL, CSA, CCC, EAC) guarantees long-lasting and trouble-free operation.
• Safety: Provides effective protection of the circuit against overload and short circuit – like most circuit breakers in this class.
• Low energy consumption: The 24VDC coil minimizes current draw during operation, resulting in energy savings.
• Suitable for continuous operation: The robust construction allows for intensive use without the risk of failure.

Technical parameters in practice

The rated operating current of the contactor is 10A at 400V, making it suitable for controlling various loads. The rated coil voltage DC is 24VDC, which ensures compatibility with popular control systems. The contactor also has overvoltage protection, which further increases its reliability and lifespan. The coil characteristics allow it to react quickly to the control signal, ensuring precise operation of the entire system.
