CA3KN40BD

The Schneider CA3KN40BD is a high-quality control relay from the TeSys K series, designed for seamless integration into control circuits. This robust component features a 4 NO (normally open) pole contact composition, ensuring reliable operation in a variety of industrial applications. With a rated operational voltage of up to 690 V and a control circuit voltage of 24 V DC, it is suitable for use in environments with a system voltage of up to 690 V at frequencies of 400 Hz or less.

The CA3KN40BD boasts a conventional free air thermal current of 10 A at temperatures up to 50°C, and an impressive rated making capacity of 110 A conforming to IEC 60947 standards. The associated fuse rating is 10 A gG, in line with both IEC 60947 and VDE 0660, ensuring adequate protection in the event of overcurrent conditions.

Mounting is made easy with options for both plate and rail support, and the relay offers a variety of screw clamp terminal connections to accommodate different cable sizes and types. The tightening torque is specified at 1.3 N.m, ensuring secure and reliable connections.

The control relay is designed with operational limits for the control circuit voltage, ranging from 0.8 to 1.15 times the rated voltage for operation, and 0.1 to 0.75 times for drop-out, providing stability across a range of conditions. The operating time is swift, with coil de-energisation and NO opening occurring within 10 ms, and coil energisation and NO closing within 30 to 40 ms.

Durability is a key feature of the CA3KN40BD, with a mechanical endurance of 20 million cycles and an operating rate of 10,000 cycles per hour. It also has an immunity to microbreaks of 2 ms, ensuring consistent performance even in demanding industrial settings.

The compact dimensions of 58 mm in height, 45 mm in width, and 57 mm in depth, along with a net weight of 0.225 kg, make this control relay an excellent choice for applications where space is at a premium.

In terms of environmental standards, the CA3KN40BD meets the requirements of BS 5424, IEC 60947, NF C 63-140, and VDE 0660. It holds product certifications from CSA and UL, and offers an IP2X degree of protection. The relay is also compliant with the EU RoHS Directive, ensuring it meets the latest environmental regulations and standards.

The Schneider CA3KN40BD control relay is a reliable and efficient solution for managing electrical circuits in industrial settings, offering both performance and durability.
