Air contactor CEM105.11-230V-50/60HZ 004652133

Air contactor – a reliable element of electrical installation

This CEM105.11-230V-50/60Hz air contactor is a solid solution for remote switching on and off of electric motors and other energy consumers. It will work both in simple applications and in more complex switching systems, star-delta or reversing. Its versatility will be appreciated by both installers and end-users looking for a reliable component for their systems.

Power and performance for demanding applications

This contactor is designed to work with loads up to 55 kW at 400 V (AC-3). The rated operating current is 105 A for AC-3 and 140 A for AC-1, making it a suitable choice for a wide range of industrial and commercial applications. Thanks to this, it can be used without fear in demanding working conditions.

Design and functionality

The contactor design allows mounting on TH35 rail or mounting plate, providing flexibility during installation. It has three main normally closed contacts, one normally open auxiliary contact (NO) and one normally closed contact (NC), allowing for the implementation of various control functions. Connection of the main contacts is done using frame clamps, which facilitates and speeds up the installation process. The control voltage is 230V AC (50/60Hz).

Additionally, the contactor is compatible with BLIME 9-105 mechanical interlocks, which allow combining contactors of different sizes. The possibility of connecting a BAM surge protector increases the safety of the installation. For precise motor protection, a dedicated overload relay from the RE series can be connected directly.
