Air contactor CEM18.10-24V-DC 004644220

Air contactor – reliable control of motors and receivers

This air contactor from the CEM series is a proven element for remote switching on and off of electric motors and other energy receivers. It finds application in a wide range, from simple control systems to more advanced configurations, such as power switching, star-delta and reversing circuits. Its solid construction and high reliability make it an ideal choice for both professional installers and end users.

Characteristics and application

The CEM18.10-24V-DC contactor is designed to operate with a DC 24V control voltage. The rated operating power for AC-3 is 7.5 kW at 400V, and the rated current AC-3 is 18A. It can also be used in AC-1 circuits, where the rated current is 32A. This makes it a versatile solution for various industrial and commercial applications. Execution with three main normally open contacts and one auxiliary normally open contact allows for the construction of complex control systems.

Advantages and benefits

• Versatility: Possibility of use in various control systems for motors and other energy receivers.
• High reliability: Guarantees stable and safe operation in demanding conditions.
• Easy installation: Possibility of mounting on TH35 rail or mounting plate facilitates installation in various configurations.
• Operating status indication: Possibility of installing front or side auxiliary contacts provides indication of the contactor operating status, which is useful in alarm and monitoring systems.
• Compatibility with accessories: Possibility of connecting BLIME mechanical locks and RE overload relays increases the functionality and safety of the system.
• Overload protection: Possibility of directly connecting an RE series overload relay provides effective protection of the motor against damage.
• Compliance with standards: Meets the requirements of PN-IEC/PN-EN 60 947 and DIN VDE 0660 standards, which confirms its safety and quality.
• Surge protector connection: Possibility of connecting a BAM surge protector to the coil terminals increases resistance to interference in the power supply network.

Additional information: CEM contactors allow mounting of up to 4 auxiliary contacts for CEM9 - CEM25 models, 6 contacts for CEM32 -CEM40 and as many as 8 contacts for CEM50-CEM105 models. The BLIME mechanical lock is compatible with CEM9 to CEM105 models, and the BLIME 9-105 02 version has an additional auxiliary contact.
