Contactor 1NO+1NC 25A 230V AC ESC227

This contactor, catalog number ESC227, is a reliable device designed for switching electrical circuits on and off. It is suitable for both home and professional installations, offering versatility and safety. Its construction allows for controlling both main and auxiliary circuits, making it an ideal solution for various applications.

Functionality and application

The device operates at 230V AC and allows switching a load of up to 25A. It has one normally open (1NO) and one normally closed (1NC) contact, providing flexibility in control circuit configuration. The contactor is particularly useful in applications requiring frequent load switching, such as lighting, heating or ventilation. Additionally, the manual mode switch offers three possibilities: constant on, automatic mode and constant off – increasing functionality and adapting the device to specific installation needs.

Characteristics and advantages

The contactor design ensures quiet operation, which is particularly important in residential buildings. Low energy consumption, thanks to innovative technology, allows reducing operating costs by up to 30%. The IP2X degree of protection guarantees basic protection against contact and ingress of solid objects. The rated operating voltage is 230…230 V AC, and the rated control voltage is also 230…230 V AC. The maximum switching capacity for incandescent lamps is 1900 W, for fluorescent lamps 950 VA (up to 1990 VA with DUO compensation and 810 VA with parallel compensation). The mounting depth is 60 mm. The device is compatible with the utilization category AC-7a/b according to EN IEC 60947-4-1.
