Air contactor CEM18.10-24V-50/60HZ 004644120

Air contactor CEM18.10-24V-50/60HZ – reliable switching of loads

This air contactor from ETI is a solid solution for remote control of electric motors and other energy consumers. It will work both in simple applications and in more complex switching systems, star-delta or reversing. The contactor design allows mounting on a TH35 rail or mounting plate, which simplifies installation in various conditions.

Parameters and application

The CEM18.10-24V-50/60HZ contactor is designed to operate at a control voltage of 24V AC (50/60Hz). Its rated operating current for AC-3 (inductive loads, e.g. motors) is 18A, allowing it to handle loads up to 7.5 kW at 400V. The rated current AC-1 (non-inductive loads) is 32A. It has three main normally closed contacts and one auxiliary normally closed contact, which enables the implementation of various control and signaling functions. Connection of the main contacts is made using frame clamps, ensuring a secure and durable connection.

Advantages and benefits for the installer and user

• Versatility: Possibility of use in various control systems – from simple on/off switching of motors to more advanced configurations.
• Easy installation: Compatibility with TH35 rails and mounting plates simplifies installation in various conditions.
• Status indication: Possibility of mounting front or side auxiliary contacts provides indication of the contactor's operating status, which is important for diagnostics and safety.
• Safety: Compliance with PN-IEC/PN-EN 60 947 and DIN VDE 0660 standards guarantees a high level of safety.
• Expandability: The ability to connect an RE overload relay directly to the contactor provides comprehensive motor protection. Additionally, a BAM surge protector can be connected to the contactor coil.
• Mechanical lock: Available mechanical lock BLIME 9-105 allows connecting contactors of different sizes, which increases installation flexibility.
• Durability: Designed to operate in ambient temperatures from -25°C to +55°C, ensuring reliable operation even in difficult conditions.
