Miniature auxiliary contactor TeSys K 4NO 24VDC coil screw terminals CA3KN40BD

Auxiliary contactor for load control

This miniature TeSys K auxiliary contactor with four normally open contacts (4NO) is a reliable solution for controlling electromagnetic loads in AC-15 and DC-13 circuits. Designed to operate with a 24V DC control voltage, it provides efficient circuit switching without consuming current during startup. Screw terminals facilitate quick and secure installation.

Construction and application

The contactor is designed for mounting on a 35 mm DIN rail or by screws, providing flexibility in installation. Its compact dimensions (width 45 mm, height 58 mm, depth 57 mm) allow for efficient use of space in control cabinets. The rated operating current of 10A at 690V DC guarantees its performance in various industrial applications. Thanks to the high operating frequency of up to 180 cycles per minute and a wide range of ambient temperatures (-25/+50°C), the contactor ensures long-term and stable operation even in harsh conditions.

Key features and benefits
