Miniature auxiliary contactor, TeSys K, 4NO, 24VAC coil, screw terminals CA2KN40B7

Auxiliary contactor – reliable circuit control

This miniature TeSys K auxiliary contactor is a key element in control systems, designed for reliable switching of auxiliary circuits. Equipped with four normally open (4NO) contacts, it allows control of various loads, from simple applications to more complex automation systems. A 24VAC powered coil ensures compatibility with a wide range of electrical installations.

Design and application

The CA2KN40B7 contactor is ideal for applications requiring frequent switching of control circuits, such as motor control, lighting or heating systems. Its compact dimensions (width 45 mm) allow for easy integration even in limited space. Mounting on a 35 mm DIN rail or with screws provides installation flexibility. Screw terminals facilitate wire connection, and the solid construction guarantees long-lasting and trouble-free operation.
