Modular contactor, DIN rail mounting, 1NO+1NC contacts, 25A ST25-11

Universal modular contactor for wide application

This modular contactor is designed for mounting on a 35 mm rail and provides reliable control of electrical circuits. The rated operating current is 25 A, making it suitable for various applications, from lighting to controlling small electrical devices. A design with one normally open (1NO) and one normally closed (1NC) contact provides flexibility in circuit configuration.

Characteristics and application

This contactor, powered by 230 V AC, is ideal for use in home installations, commercial buildings and light industry. Its compact dimensions – 2 module width and 65 mm depth – allow for easy mounting in switchboards. The main purpose of the contactor is to remotely switch the load on and off, which increases comfort and safety of the installation. Therefore, it is perfect for home automation systems, lighting or heating control.

Key features and benefits

• High switching capacity: The maximum switching capacity for incandescent lamps is as high as 4000 W, allowing control of even larger loads.
• Safety: IP20 protection degree provides basic protection against contact and ingress of solid objects.
• Solid construction: Made of high-quality materials, guarantees long-lasting and reliable operation.
• Easy installation: Mounting on a standard 35 mm rail is simple and intuitive for both professionals and less experienced users.
• Status indication: A red indicator in the window informs about the current switching status of the contactor – visual control without the need to open the housing.
• Compliance with standards: Meets the requirements of IEC 61095 standard, which confirms its safety and quality.
• Low energy consumption: Power consumption at 2.2 W minimizes energy losses in the installation.
• Wide operating temperature range: Allows operation in difficult environmental conditions (-25°C to +50°C).
• Suitable for wires with a cross-section of up to 4 mm²: Ensures compatibility with most standard electrical installations.

Let's remember that a modular contactor is an element ensuring safe and efficient control of electrical circuits – investing in its quality translates into long-term and trouble-free operation of the entire installation.
