Air contactor CEM25.10-24V-DC 004645220

Air contactor – reliable switching on and off of loads

This air contactor from the CEM series is a proven component for remote control of electric motors and other energy consumers. Thanks to its design and expandability, it finds application in various power supply systems, including power switching systems (SZR) and star-delta starters. It is a solid solution for both professionals and end users who need reliable control of electrical loads.

Characteristics and application

The CEM25.10-24V-DC contactor is designed to operate with a 24V DC control voltage. Its AC-3 rated current is 25A, allowing it to handle loads up to 11 kW (at 400V). The rated AC-1 operating current is 45A. This makes this contactor ideal for use in industry, construction and automation systems. The contactor design allows mounting on TH35 rail or mounting plate, providing installation flexibility.

Advantages and benefits

• Versatility: Can be used in power switching systems (SZR), star-delta starters and reversing systems.
• Status indication: Possibility of mounting front and side auxiliary contacts for indicating the operating status of the contactor – useful in alarm or device monitoring systems. It is possible to mount up to 4 auxiliary contacts (for CEM9 - CEM25 models) or even 6 or 8 for larger models.
• Safety: Possibility of connecting a BAM surge protector to the contactor coil terminals increases the safety of the installation.
• Compatibility: Possibility of directly connecting a dedicated overload relay from the RE series to protect the motor against overload.
• Mechanical interlock: Available mechanical interlock BLIME 9-105 allows connecting contactors of different sizes (CEM9 to CEM105), which facilitates the construction of complex control systems. The BLIME 9-105 02 version has an additional auxiliary contact.
• Compliance with standards: Meets the requirements of PN-IEC/PN-EN 60 947 and DIN VDE 0660 standards, which guarantees its reliability and safety of use.
• Construction: Has three normally closed main contacts and one normally open auxiliary contact, as well as zero normally open auxiliary contacts.
• Wide temperature range: Operation in ambient temperature from -25°C to +55°C ensures the possibility of use in various environmental conditions.

This contactor is not only a control element, but also an element ensuring the safety and reliability of the entire electrical installation. Its solid construction and compliance with standards make it an ideal choice for both professional installers and end users looking for a proven solution for controlling electrical loads.
