The Schneider TeSys CAK Series Control Relay, with part number CA2KN31P7, is a highly reliable and efficient solution for managing control circuits within a wide range of industrial applications. Designed for DIN rail mounting, this compact device measures 45 x 57 x 58 mm and is equipped with a 230 V ac standard coil, making it suitable for use in systems with a rated operational voltage of up to 690 V and a frequency of up to 400 Hz.
This control relay features a 4NO (4 Normally Open) contact composition, providing a versatile interface for controlling various loads. The device is capable of handling a conventional free air thermal current of 10 A at 50°C, and it has an impressive rated making capacity of 110 A conforming to IEC 60947 standards. For added safety and compliance, it is associated with a 10 A gG fuse rating.
Connection to the relay is made simple with its screw clamp terminals, which can accommodate cables ranging from 1.5 to 4 mm² in size, whether solid or flexible, with or without cable ends. The tightening torque for these terminals is specified at 1.3 N.m, ensuring secure and reliable connections.
The control relay's operational limits for the control circuit voltage are between 0.8 to 1.15 times the rated coil voltage for operation and 0.2 to 0.75 times for drop-out, providing stability across various conditions. It also boasts a mechanical durability of 10 million cycles and an operating rate of up to 10,000 cycles per hour, highlighting its robustness and longevity in demanding environments.
With an IP20 degree of protection, the CA2KN31P7 is safeguarded against solid objects larger than 12 mm, although it should be installed in enclosures to protect against dust and moisture for industrial settings. The relay's design also includes features to withstand vibrations and shocks, ensuring consistent performance even in challenging conditions.
The Schneider CA2KN31P7 is a Green Premium product, reflecting Schneider Electric's commitment to sustainable development and compliance with environmental regulations. It is free of substances of very high concern (SVHC) above the threshold, mercury-free, and adheres to the EU RoHS Directive.
This control relay is an essential component for professionals seeking a dependable and environmentally conscious solution for their control circuit needs in industrial automation systems.
