Contactor 100A, 230V, 2xNO contacts ST100-20

Modular contactor for electrical installations

This electromagnetic contactor, designed for mounting on a 35mm rail, is a reliable solution for controlling electrical circuits. The rated operating current of 100A and the coil supply voltage of 230V AC make it ideal for various applications in residential and commercial buildings. The design with two normally open contacts (2NO) allows control of receivers requiring more power.

Characteristics and application

The ST100-20 contactor is used for frequent switching of electrical circuits, ensuring safe and efficient operation of the installation. Its modular construction (3 modules wide) facilitates mounting and integration with existing switchboards. Application in lighting circuits, heating circuits or motor control are just some of the possibilities. Thanks to its high switching durability (1x10⁵ electrical cycles and 1x10⁶ mechanical cycles), it guarantees long-term and trouble-free operation.

Key features and benefits

• High switching capacity: The maximum switching power for incandescent bulbs is as high as 22000 W, allowing control of even demanding receivers.
• Safety: Protection class IP20 provides basic protection against contact and ingress of solid objects.
• Easy installation: Modular design facilitates quick and easy mounting on a standard 35mm rail.
• Durability: High switching durability guarantees long device life, minimizing replacement costs.
• Solid construction: Made of high-quality materials, resistant to mechanical damage and environmental conditions (operating temperature from -25°C to +50°C).
• Screw terminals: Allow connection of wires with a cross-section of up to 25 mm², ensuring a secure electrical connection.
• Insulation voltage: Insulation voltage of 4kV provides additional safety.
• Compliance with standards: Meets the requirements of IEC 61095 standard, confirming its quality and safety.

Please remember that contactors of this type are an element of the electrical installation and their installation should be carried out by a qualified electrician in accordance with applicable regulations.
