Miniature auxiliary contactor, TeSys K, 2NO 2NC, 24VDC coil, screw terminals CA3KN22BD3

Auxiliary contactor – reliable load control

This miniature auxiliary contactor from the TeSys K series is a key element in electromagnetic load control systems. Designed to operate at 24V DC, it offers a configuration of 2 normally open (NO) and 2 normally closed (NC) contacts, providing flexibility in building control circuits. Its compact dimensions and the possibility of mounting on a DIN rail or with screws make it ideal for use in electrical distribution boards and control cabinets.

Construction and application

The CA3KN22BD contactor is designed to work with various types of starters, both reversing and direct-on-line, as well as star-delta switches. It provides reliable switching of control circuits, protecting devices from overload and short circuit. Made of high-quality materials, it guarantees long life and stable operation even in harsh environmental conditions. Screw terminals facilitate connection of wires, and the lack of an LED indicator minimizes the risk of misinterpreting the contactor's status.
