Air contactor CEM40.00-42V-50/60HZ 004647105

Air contactor – reliable control of motors and loads

This three-pole ETI Polam CEM40.00-42V-50/60Hz air contactor is a solid solution for remote switching of electric motors and other energy consumers. It will work in both industrial installations and commercial buildings or workshops where reliability and efficient load control are required. Thanks to the possibility of cooperation with accessories, such as mechanical locks, the contactor can also be used in power switching systems, star-delta and reversing systems.

Key features and applications

The CEM40.00-42V-50/60Hz contactor is distinguished by its high current capacity, making it an ideal choice for controlling various devices. The AC-3 rated current is 40A at 400V, and the AC-3 rated power is 18.5 kW. The AC-1 rated current reaches 60A, allowing for trouble-free control of resistive loads. The control voltage of 42V AC (50/60Hz) ensures compatibility with a wide range of control systems.

• Versatility: Suitable for controlling electric motors, heaters, lighting and other energy consumers.
• Safety: Provides effective protection of the installation against overload and short circuit.
• Durability: Solid construction guarantees long-lasting and trouble-free operation in harsh industrial conditions.
• Easy installation: Possibility of mounting on TH35 rail or mounting plate facilitates installation and integration with existing systems.
• Compatibility: Possibility of connecting an overload relay RE from the ETI Polam series for additional motor protection.

Construction and technical parameters

The contactor has been designed with ease of use and integration with various electrical systems in mind. It has frame terminals for connecting the main contacts, which ensures a secure and durable connection of the wires. The control voltage AC (42…42V) makes the contactor compatible with most standard control systems. The contactor housing is made of high-quality materials, which ensures its durability and resistance to mechanical damage and environmental factors.

The AC-3 rated current (400V) is 40 A, and the AC-1 rated current (400V) reaches 60 A. The AC-3 rated power (400V) is 18.5 kW, and the AC control voltage (50/60Hz) is 42 V. The contactor has 3 normally open main contacts and uses frame terminals to connect the main contacts.

The contactor meets the standards PN-IEC/PN-EN 60947 and DIN VDE 0660, which confirms its safety and compliance with applicable standards. The ambient operating temperature is in the range of -25°C to +55°C, which allows its use in various environmental conditions.
