Air contactor CEM9.10 42V 50/60HZ 004642125

Air contactor CEM9.10 – a reliable automation component

The CEM9.10 contactor is a solid and proven device designed for remote switching of electric motors and other energy consumers. It will work in both simple applications and more complex control systems, such as power switching, star-delta and reversing circuits. Its versatility will be appreciated by both professional installers and end-users looking for a reliable solution for controlling loads.

Characteristics and application

This contactor from the CEM series is characterized by a compact design and high efficiency. It is designed to operate at a control voltage of 42V AC (50/60Hz), making it an ideal choice for many standard installations. Its AC-3 rated current of 9A allows it to handle motors up to 4 kW, and the AC-1 current reaches 25A. This makes it suitable for a variety of industrial and commercial applications – from controlling pumps and fans to switching on machines and production equipment.

Advantages and benefits

• Versatility: The ability to use in power switching, star-delta and reversing circuits increases the range of applications for the contactor.

• Status indication: The availability of auxiliary contacts (1NO) allows for easy indication of the contactor's operating status, which is particularly important in alarm or device monitoring systems.

• Easy installation: The contactor design allows for mounting on TH35 rail or mounting plate, making installation easier in various conditions.

• Compatibility: The ability to connect an overload relay from the RE series directly to the contactor provides effective protection of the motor against overload.

• Mechanical interlock: Optional mechanical interlock BLIME 9-105 allows connecting contactors of different sizes (CEM9 to CEM105), which increases the flexibility of installation design.

• Compliance with standards: Meets the requirements of PN-IEC/PN-EN 60 947 and DIN VDE 0660 standards, which guarantees safety and reliability.

• Protective coil connection: The possibility of connecting to the surge protector coil terminals BAM increases the safety of the installation.

Construction and parameters

The contactor has three normally closed main contacts and one normally open auxiliary contact (1NO). The connection of the main contacts is made using frame terminals, which ensures a secure and durable connection of the wires. The control voltage is 42V AC (50/60Hz). The ambient operating temperature is in the range of -25°C to +55°C, which allows it to be used in various environmental conditions. Additional auxiliary contacts (front or side) can be installed directly on the moving part of the main contacts – a maximum of 4 pieces for CEM9-CEM25 models and 6 or 8 pieces for larger models.
