Contactor 2NO 25A 24V AC ESD225

Universal contactor for lighting and heating control

This 2NO 25A 24V AC contactor (ESD225) is a reliable solution for controlling electrical circuits in residential and commercial buildings. It is suitable for both lighting and heating installations, as well as ventilation systems. Its compact size (1 module wide) allows for easy mounting in distribution boards.

The contactor offers three operating modes – constant on, automatic, and constant off – which increases its functionality and allows it to be adapted to different needs. A manual mode switch simplifies configuration and installation testing. This allows installers to quickly and efficiently adapt the device to specific project requirements.

Characteristics and application

The ESD225 contactor is designed to work with AC-7a/b loads, which means it is perfectly suited for controlling inductive loads such as motors, transformers and fluorescent lamps. The maximum switching capacity for incandescent bulbs is 1900 W, and for fluorescent lamps – up to 1990 VA (with DUO compensation). The rated current of the device is 25 A at 230 V AC.

The contactor design ensures high reliability and durability. The IP2X degree of protection protects against contact with live parts and the ingress of solid objects larger than 12.5 mm. Low power consumption (4W) translates to energy savings, which is particularly important in long-term applications. The quiet operation of the device makes it ideal for use in residential premises.

Advantages and benefits

• Versatility: three operating modes (constant on, automatic, constant off) allow adaptation to various applications.
• Compact dimensions: occupies only 1 module in the distribution board, making installation easier even in limited spaces.
• High reliability: solid construction and high quality workmanship guarantee long-term, trouble-free operation.
• Energy saving: low power consumption minimizes operating costs.
• Quiet operation: ideal for use in residential and office premises.
• Universal application: possibility of controlling lighting, heating, ventilation and other inductive loads.
• Easy installation: intuitive design simplifies installation and configuration by professionals.
• Compliance with standards: ensures safe and compliant operation of the electrical installation.

The rated current is 25 A at 230 V AC, and the control voltage is 24 V AC. The contactor has 2 normally open (NO) contacts and no normally closed (NC) contacts. The maximum switching capacity for incandescent bulbs is 1900 W, and for fluorescent lamps – up to 1990 VA (with DUO compensation). The mounting depth of the contactor is 60 mm.

The ESD225 contactor is an optimal solution for installers looking for a reliable and versatile device for controlling electrical circuits and for end-users who value comfort and safety.
