Modular contactor for rail, 4xNO contacts, 25A, 24V DC ST25-40-24ACDC

Modular contactor – reliable circuit switching

This modular contactor from F&F is a key element in automation and control systems. Designed for mounting on a 35 mm rail, it provides safe and efficient switching of electrical circuits. Thanks to its compact size (2 modules wide), it is ideal for switchboards with limited space. The design with four normally open contacts (4NO) allows you to control various loads, and the rated current of 25A guarantees reliability even under higher loads.

Functionality and application

This contactor is a universal solution, operating with both alternating current (AC) and direct current (DC). The coil voltage of 24V AC/DC makes it compatible with a wide range of control systems. It can be used in lighting, heating, ventilation installations, as well as in controlling motors and other electrical devices. Its solid construction and high durability (1x10⁵ electrical switching cycles, 1x10⁶ mechanical) ensure long-term and trouble-free operation.

Key features and benefits

• Versatile control voltage: The ability to power the coil with both AC and DC voltage increases installation flexibility.
• High switching capacity: Rated current of 25A and maximum switching capacity for incandescent lamps up to 9000W allow for servicing demanding loads.
• Compact dimensions: A width of only 2 modules makes it easy to install in tight switchboard spaces.
• Safety: Compliance with IEC 61095 standard and IP20 protection degree guarantee safe operation.
• Durability: High electrical and mechanical durability ensures a long service life of the device, minimizing maintenance costs.
• Easy installation: Mounting on a standard 35 mm rail is quick and easy, saving time during installation.
• Universal contacts: Four normally open contacts (4NO) provide a lot of freedom in configuring control circuits.
• Screw terminals: Ensure a secure connection of wires with a cross-section of up to 4 mm².

This contactor is a solid choice for both professional installers and end-users looking for a reliable solution for controlling electrical circuits. Its versatility, durability and ease of installation make it an ideal component in many building and industrial automation applications.
