CA3KN313BD3

The Schneider CA3KN313BD3 is a robust control relay from the TeSys K series, designed to facilitate the management of control circuits. This component is engineered to handle rated operational voltages up to 690V and is suitable for frequencies up to 400 Hz, making it a versatile choice for a wide range of industrial applications.

Featuring a 4-pole configuration with 3 normally open (NO) and 1 normally closed (NC) contacts, it offers flexibility in circuit design. The control circuit type is DC standard, with a control circuit voltage of 24V DC, ensuring compatibility with common industrial control voltages.

The relay is equipped with a built-in bidirectional peak limiting diode suppressor, enhancing its resilience against voltage spikes and ensuring stable operation. It has a conventional free air thermal current rating of 10A at 50°C and an impressive rated making capacity of 110A conforming to IEC 60947 standards.

Mounting is made easy with options for plate or rail support, and the spring terminals accommodate cables ranging from 0.75 to 1.5 mm², both solid and flexible without cable end. The control relay is designed with operational voltage limits to ensure reliable performance, with operational ranges from 0.8 to 1.15 times the control voltage and drop-out ranges from 0.1 to 0.75 times the control voltage, both at temperatures below 50°C.

The CA3KN313BD3 boasts a mechanical durability of 20 million cycles and a maximum operating rate of 10,000 cycles per hour, testifying to its longevity and reliability in demanding environments. It also features immunity to microbreaks of 2 ms, an inrush power of 3W at 20°C, and a heat dissipation of 3W, which contribute to its stable thermal performance.

With a minimum switching voltage of 17V and a minimum switching current of 5 mA, this control relay ensures precise operation even at low thresholds. The non-overlap distance of 0.5 mm and insulation resistance greater than 10 MOhm further enhance its electrical robustness.

The compact dimensions, with a height of 58 mm, width of 45 mm, and depth of 57 mm, along with a net weight of 0.225 kg, make the CA3KN313BD3 an easy fit in various control panels and equipment.

This control relay is compliant with several international standards, including EN/IEC 60947-4-1, and holds product certifications such as CSA and UL. It also aligns with sustainability objectives, being a Green Premium product that is REACh and RoHS compliant, mercury-free, and free of toxic heavy metals.
