Modular contactor 20A ST20-20

Universal modular contactor 20A – reliable circuit control

This modular contactor with a rated current of 20A is a compact and efficient solution for controlling electrical circuits. It is suitable for both home and commercial installations where reliability and ease of installation are required. Its construction, based on IEC 61095 standard, guarantees safety and compliance with applicable standards.

Construction and application

The contactor is designed for frequent switching of electrical circuits. It has two normally open contacts (2NO), allowing control of various loads. Mounting on a standard 35 mm rail facilitates integration with existing electrical infrastructure. Compact dimensions – only 1 module (18 mm) – allow saving space in the switchboard. Screw terminals allow connection of wires with a cross-section of up to 4 mm², ensuring a stable connection.

• Versatile application: ideal for controlling lighting, heaters, small motors (up to 1.3 kW in AC3 category at 230V) and other electrical devices.
• Durable construction: withstands up to 100,000 electrical and one million mechanical switching cycles, ensuring long-term use without frequent replacement.
• Safety: insulation voltage of 4 kV guarantees protection against breakdown and short circuit. Protection degree IP20 provides basic protection against contact.
• Energy efficiency: coil power consumption is only 2.2 W, minimizing energy losses.
• Wide operating temperature range: from -25°C to +50°C allows operation in various environmental conditions.

Thanks to its versatility and reliability, this contactor is an excellent choice for both professional installers and end-users looking for a solid solution for controlling electrical circuits. Its compact size makes it easy to install even in tight spaces, and the high quality of workmanship guarantees long-lasting and trouble-free operation.
