Miniature auxiliary contactor, TeSys K, 4NO, 220VDC coil, screw terminals CA3KN40MD

TeSys K miniature auxiliary contactor – reliable circuit control

This miniature auxiliary contactor from the TeSys K series is a key element in control systems, providing efficient and safe circuit switching. Designed to operate at 220VDC, it is ideal for applications requiring frequent switching of the load. The design with four normally open contacts (4NO) allows for flexible configuration of auxiliary circuits, and screw connections guarantee solid and reliable wire connections.

Construction and application

The CA3KN40MD contactor is designed for mounting on a DIN rail or screwing, which facilitates its integration with existing installations. Its compact dimensions (57 mm depth, 58 mm height, 45 mm width) allow for efficient use of space in switchboards. Designed to operate with a rated current of 10A (at 400V), it is perfectly suited for controlling various types of receivers, such as motors, heaters or lighting. The use of a 220V DC coil ensures compatibility with a wide range of power sources.
