## Summary description

The F&F ST25-02-24DC is a modular contactor designed for DIN rail mounting. It features a 25A rated current and operates on a 24V DC control voltage. Equipped with 2 normally closed (NC) contacts, this device is suitable for switching electrical circuits in residential and industrial automation systems, ensuring reliable control and power distribution.

## Long description

The F&F ST25-02-24DC is a high-quality modular contactor engineered for reliable switching of electrical circuits in both residential and industrial environments. Designed for seamless integration into electrical cabinets, this device mounts directly onto standard DIN rails, making it an efficient solution for modern automation systems. With a rated current of 25A and a control voltage of 24V DC, it provides stable performance for various power distribution tasks.
Advantages
This modular contactor stands out due to its robust construction and precise engineering, which ensure long-term operational reliability. The use of two normally closed contacts allows for specific circuit configurations where the default state is closed, providing versatility in control logic. Its compact modular design saves valuable space in distribution boards, while the 24V DC coil operation enhances safety and compatibility with low-voltage control systems.
Suitable for
Residential electrical automation systems
Industrial control panels and power distribution
Lighting control circuits
Heating and ventilation systems
Automation of electrical loads requiring normally closed contact logic
This device may not be suitable for applications requiring high-frequency switching beyond its mechanical endurance limits or for environments with extreme vibrations or temperatures outside the specified operating range. It is also not intended for use in circuits exceeding the 25A rated current capacity.
Key specifications
Rated current: 25A
Control voltage: 24V DC
Contact configuration: 2 Normally Closed (NC)
Mounting type: DIN rail
Design: Modular
To install the contactor, ensure the power supply is disconnected. Mount the device onto a standard 35mm DIN rail within the distribution board. Connect the control wires to the coil terminals and the load wires to the power terminals, ensuring all connections are tightened to the manufacturer's torque specifications. Once installed, verify the wiring against the circuit diagram before restoring power.
What to consider before purchase
Ensure the control voltage of your system matches the 24V DC requirement
Verify that the 25A current rating is sufficient for your specific load
Confirm that the normally closed contact configuration aligns with your control logic
Check available space on the DIN rail for modular installation
For optimal performance and longevity, ensure the contactor is installed in a well-ventilated enclosure to prevent overheating. Regularly inspect the terminal connections for tightness during routine maintenance to maintain electrical integrity.
