Modular contactor with manual control, DIN rail mounting 63A, 4NO contacts ST63-40-M

Modular contactor with manual control – reliable circuit switching

This modular contactor from F&F, model ST63-40-M, is a solid and versatile device designed for safe and efficient control of electrical circuits. Mounted on a standard 35mm rail, it is ideal for both domestic and industrial installations. Its design combines remote and manual control functions, increasing flexibility and facilitating diagnostics.

Construction and application

The ST63-40-M contactor is characterized by four normally open contacts (4NO), allowing control of various loads. The rated operating current of 63A and the maximum switching capacity for lamps of 24000W make it a suitable solution for high-power loads. Manual operation, thanks to the slider, is particularly useful during maintenance or system control failures. The device is designed to operate in alternating current (AC) networks with a voltage of 230V.

Key features and benefits

• Versatility: The combination of remote and manual control provides flexibility in various situations. The installer will appreciate the ability to test the circuit without the need to connect external control, and the end user will gain confidence in operation even in the event of automation system failure.
• High reliability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation. The IP20 protection class provides protection against touch and dust.
• Easy installation: The modular design and mounting on a standard 35mm rail greatly facilitate installation and integration with existing systems.
• Safety: The rated insulation voltage of 500V AC and the high impulse voltage withstand capability (4kV) ensure safe use.
• Wide application: Ideal for controlling lighting, heaters, pumps, fans and other electrical devices requiring high current capacity.
• Status indication: The activity indicator allows for quick visual identification of the contactor's on/off status.

The ST63-40-M contactor is an optimal solution for professionals looking for a reliable and versatile device for controlling electrical circuits, and for end users who value safety and functionality. Its solid construction and ease of installation make it an ideal choice for both new installations and modernization of existing systems.
