Air contactor CEM150E.22-250V-AC/DC 004654241

Air contactor – reliable switching on and off of circuits

This air contactor, catalog number 004654241, is a robust solution for remote control of electric motors and other energy consumers. Designed to operate in demanding industrial conditions, it provides safe and efficient switching of high-power circuits. Its versatility makes it suitable for both simple systems and more complex power switching systems.

Design and operating parameters

The CEM150E.22-250V-AC/DC contactor is distinguished by its easy expandability. As standard, it is equipped with two auxiliary contact blocks (1NO+1NC), and additional blocks can be mounted on both sides of the device. The AC-3 rated current at 400V is 150A, allowing operation of motors up to 75 kW. The rated AC-1 operating current at 400V is 225A. A wide control voltage range (AC/DC 208…250V) increases installation flexibility. The connection of the main contacts is realized via busbar connection, which facilitates assembly and ensures a secure connection.

Application and benefits

Contactors of this series are ideal for applications in industry where reliability and safety are required. They can be used in power switching circuits (SZR), star-delta circuits and reversing circuits. Thanks to compliance with PN-IEC/PN-EN 60947 and DIN VDE 0660 standards, you can be sure that the device meets stringent quality and safety requirements. Additionally, the possibility of mounting thermal relays via busbar connections provides effective protection against overload. Cage clamps TBE (in CEM112 - CEM300 models) facilitate the connection of wires of different diameters, and CCEM terminal covers protect against accidental contact with conductive elements.
