Miniature auxiliary contactor, TeSys K, 3NO 1NC, 42VAC coil, screw terminals CA2KN31D7

Auxiliary contactor – a reliable automation element

This miniature TeSys K auxiliary contactor is a key component in control systems, designed to work with electromagnetic loads. Equipped with three normally open contacts (3NO) and one normally closed contact (1NC), it provides flexibility in configuring control circuits. Designed to operate at 42VAC, it is ideal for applications requiring precise and reliable switching.

Design and application

This contactor has been designed for easy mounting on a 35 mm DIN rail or with screws, which greatly simplifies installation and servicing. Screw terminals ensure secure and durable wire connections. Its compact dimensions (width 45 mm, depth 68 mm, height 58 mm) allow for efficient use of space in the switchgear cabinet. Rated current of 10A at 400V and the ability to operate at up to 690V AC make it a versatile solution for various industrial and construction applications.
