Air contactor CEM180.22-230V-50/60HZ 004655143

Air contactor – reliable switching of motors and loads

This CEM180.22-230V-50/60Hz air contactor is a solid solution for remote control of electric motors and other energy consumers. It will work in both simple applications and more advanced switching systems, star-delta or reversing. Its construction ensures reliable operation and long life, which translates to minimal downtime in the installation.

Construction and application

This contactor, with a rated current of 180A for AC-3 loads and a power of 90kW at 400V, is designed to operate with a control voltage of 230V AC (50/60Hz). It has three main normally open contacts and two auxiliary normally open and two normally closed contacts (2NO+2NC), which provides great flexibility in configuring control circuits. The connection of the main contacts is made using a busbar connection, which facilitates installation and ensures a secure connection.

Thanks to the possibility of mounting additional auxiliary contact blocks, the contactor can be adapted to specific application needs. The use of thermal relays, connected via busbar connections, allows for effective protection against overload. The built-in varistor protects the coil against overvoltage, increasing the safety and durability of the device.

Key features and benefits

• High efficiency: Rated current of 180A (AC-3) and power of 90kW (AC-3) allow for handling demanding loads.
• Versatility: Can be used in various control systems – from simple motor on/off to more complex SZR, star-delta and reversing configurations.
• Safety: Built-in varistor protects the coil from damage caused by overvoltage.
• Flexibility: The ability to expand with additional auxiliary contact blocks increases the functionality of the device.
• Easy installation: Busbar connection facilitates the connection of the main conductors, and cage clamps (in CEM112 - CEM300 models) allow the connection of conductors of different diameters.
• Overload protection: Compatible with thermal relays providing effective protection of the installation.
• Standard equipment: Two auxiliary contact blocks (1NO+1NC) as standard – saving time and installation costs.

The CEM180.22-230V-50/60Hz contactor is a proven choice for both professional installers and end users looking for a reliable solution for controlling motors and other electrical loads.
