Air contactor CEM12.10-24V-DC 004643220

Air contactor CEM12.10-24V-DC – reliable switching of loads

This air contactor, catalog number 004643220, is a key element in control systems for electric motors and other energy consumers. Designed to operate with a DC 24V control voltage, it provides reliable remote switching of devices with a power of up to 5.5 kW (for AC-3, 400V). The wide range of applications for CEM contactors includes not only direct motor control, but also power switching, star-delta and reversing circuits.

Construction and operating parameters

The CEM12.10-24V-DC contactor is characterized by a solid construction and high electrical parameters. It has three normally closed main contacts and one normally open auxiliary contact, which allows its integration with various control systems. The connection of the main contacts is made using frame terminals, which ensures convenient and safe installation. The AC-1 rated current is 25A, and the AC-3 rated current (for inductive loads) is 12A.

Versatility and compatibility

This contactor is compatible with accessories such as BLIME mechanical interlocks, which allow the combination of contactors of different sizes in one system. The possibility of connecting a BAM overvoltage protection to the contactor coil further increases the safety of the installation. The contactor design allows mounting on both TH35 rail and mounting plate, providing flexibility in choosing the installation location. Additionally, it is possible to connect a dedicated overload relay from the RE series to ensure comprehensive motor protection.

Application and standards

The CEM12.10-24V-DC contactor meets the requirements of PN-IEC/PN-EN 60 947 and DIN VDE 0660 standards, which guarantees its safety and reliability. It is an ideal solution for both professional installers and end-users looking for a proven element for controlling electrical loads. Thanks to its construction and technical parameters, it finds application in a wide range of industrial and commercial applications.
