Contactor 100A, 230V, 4xNO contacts ST100-40

Modular contactor ST100-40 is a reliable device designed for remote switching of electrical circuits. It finds application in both domestic and industrial installations where control over large loads is required. Its modular design simplifies mounting on a standard 35 mm rail, saving space in the distribution board.

This four-pole contactor (4xNO) with a rated current of 100A and a coil voltage of 230V AC allows control of various receivers – from lighting, through electric heaters, to motors. A switching capacity of up to 38000 W (for incandescent bulbs) makes it a suitable choice for demanding applications. The contactor's construction ensures safe and efficient operation, and the IP20 protection degree protects against contact and ingress of solid objects.

Construction features and application:

• Modular construction: occupies 6 modules on a TH35 rail, making it easy to integrate with an existing installation.
• Four normally open contacts (4xNO): allow independent control of multiple circuits.
• Designed to operate with 230V AC voltage: standard supply voltage in most installations.
• High switching capacity: allows operation of high-power devices.
• Solid construction: ensures long-lasting and trouble-free operation.
• Wide operating temperature range (-25°C to +50°C): allows use in various environmental conditions.

The ST100-40 contactor is an ideal solution for installers looking for a reliable and easy-to-install device for remote control of electrical circuits. For end-users, this means convenience and safety in energy management in the home or company. Thanks to its high mechanical durability (1x10⁶ cycles) and electrical durability (1x10⁵ cycles), the contactor guarantees long-term operation without frequent replacement. Screw terminals allow connection of wires with a cross-section of up to 25 mm², ensuring a safe electrical connection.
