Modular contactor for remote control of loads

This 25-amp modular contactor iCT50-25-04-230 is a reliable solution for remote control of various loads, such as lighting, small motors (e.g., in fans or mixers) and HVAC systems. The device, catalog number A9C20837, is designed for DIN rail mounting and offers flexibility thanks to the possibility of expanding with additional auxiliary contacts. Its compact dimensions – 2 module width and 43.5 mm installation depth – allow for efficient use of space in the distribution board.

Functionality and operating parameters

The contactor operates at a rated voltage of 400 VAC and a control voltage of 220-240 VAC. It has 4 normally open (NO) contacts and is designed for a frequency of 50 Hz. Its switching capacity is impressive: up to 8550 W for incandescent lamps, 3600 VA for fluorescent lamps (and even 7200 VA with DUO compensation). This allows it to be used in a wide range of applications. The rated current of 25A ensures safe and efficient operation with various loads. The IP20 degree of protection guarantees basic protection against touch and ingress of solid objects.

Advantages for installers and users

The device is compatible with Acti9 accessories, making it easy to integrate with existing lighting, heating and ventilation control systems. Electrical endurance reaches up to 100,000 cycles for AC-7A/AC-1, which translates to long life and reliability. In addition, the contactor has an optical indicator of the status of the output contacts, facilitating diagnostics and maintenance. Remote control allows convenient management of loads from anywhere. Using this contactor is not only user comfort, but also saving time and costs related to service and component replacement.
