The Schneider Electric TeSys K CA2KN Contactor is designed for automation professionals and system integrators seeking a compact, reliable control solution for industrial machinery and control circuits. Its key benefit lies in its high performance within a small footprint, offering a cost-effective solution for simple applications. A minor caveat is its operating temperature range, which is standard but requires consideration in extreme environments. This 10A, 2NO+2NC relay ensures dependable operation with a 690V AC contact voltage rating and a 24V AC control voltage, featuring screw terminals for secure connections and DIN rail mountability for easy integration.

The TeSys K CA2KN Contactor is ideal for simple control systems, switching contactor or relay coils, and powering control and signaling equipment in industrial, building, and infrastructure applications, especially in zones sensitive to noise or with disturbed mains supplies.
The CA2KN22B7 model features screw terminals for secure and reliable connections.
The operating temperature range for this contactor is -25°C to +50°C. While robust, it may not be suitable for applications exceeding these limits without additional environmental controls.
The contact voltage rating for this product is 690 V AC, making it suitable for high-power load applications within its current limits.
The contactor can be mounted on a standard 35mm DIN rail or directly to a panel using screws. Ensure it is securely fastened for optimal performance and longevity.
Yes, the TeSys K series includes low-consumption coil versions with built-in suppression that are suitable for use with programmable controllers.
For AC voltage types, the power consumption is 4.5 VA. For DC voltage types, it is 2.4 W.
Verify that the control voltage supplied matches the coil voltage rating (24V AC for CA2KN22B7). Check for loose wiring connections at the coil terminals (A1/A2) and ensure the control circuit is active.
Inspect for any short circuits in the control wiring. Ensure the control voltage source is properly de-energized. Check if the contactor is properly seated on the DIN rail or if mounting screws are secure, as improper mounting can sometimes affect operation.
This is a serious fault usually caused by overload or short circuits. The contactor will likely need to be replaced. Investigate the cause of the overload in the main circuit to prevent recurrence.
Ensure the correct control voltage is applied. If the voltage is correct and the coil is overheating, it may indicate an internal fault or a short circuit within the coil; replacement may be necessary.
Setup:
The TeSys K CA2KN Contactor is designed for straightforward installation. It can be mounted directly onto a standard 35mm DIN rail or via screw fixing. Ensure proper wiring according to the terminal markings (typically marked with coil voltage, and contact configurations like A1/A2 for coil, and numbered contacts for NO/NC). Secure all connections firmly to the screw terminals.
Compatibility:
This contactor is compatible with a wide range of market voltages for its control circuit. The CA2KN22B7 model specifically operates with a 24V AC control voltage. It is designed to work seamlessly within automation systems that adhere to standards like IEC 60947. Ensure your control system's voltage output matches the contactor's coil voltage requirement.
Care:
To maintain optimal performance, regularly inspect the contactor for any signs of wear, damage, or excessive heat. Keep the area around the contactor clean and free from dust and debris. The unit is IP2x protected, meaning it offers protection against solid objects greater than 12.5mm and dripping water, but avoid exposure to excessive moisture or corrosive environments. Cleaning can be done with a dry or slightly damp cloth; avoid using solvents. Periodically check terminal connections for tightness, especially after periods of vibration.
