## Long description

The F&F ST25-11-24DC modular contactor is a high-quality electromechanical switching device engineered for the reliable control of electrical circuits in both residential and industrial environments. Designed for seamless integration into standard electrical distribution boards, this contactor operates with a 24V DC control voltage and supports a rated current of 25A. It features a versatile contact configuration consisting of one normally open (NO) and one normally closed (NC) contact, making it an essential component for automated power management systems.
Advantages
This modular contactor offers exceptional operational reliability and durability, ensuring consistent performance even under frequent switching cycles. Its compact design allows for efficient space utilization within electrical enclosures, while the standard DIN rail mounting mechanism facilitates quick and straightforward installation. The use of high-grade materials ensures long-term stability and safety, providing a robust solution for managing various electrical loads without the need for complex maintenance.
Suitable for
Automated lighting control systems
Heating and ventilation circuit management
Control of small electric motors
General purpose power switching in distribution boards
This device is not suitable for applications requiring AC control voltages, as it is specifically engineered for 24V DC operation. It should not be used in environments exceeding its rated current capacity of 25A or in circuits where high-frequency switching exceeds the mechanical lifespan of the internal contact mechanism.
Key specifications
Rated current: 25A
Control voltage: 24V DC
Contact configuration: 1 NO + 1 NC
Mounting type: DIN rail (35 mm)
Modular design for standard distribution boards
To install the contactor, ensure the power supply is disconnected. Mount the device onto a standard 35 mm DIN rail within the distribution board. Connect the control circuit wires to the designated coil terminals and the load circuit wires to the power terminals, ensuring all connections are tightened securely according to the specified torque requirements. Once installed, verify the wiring against the circuit diagram before restoring power to the system.
What to consider before purchase
Verify that your control system provides a 24V DC signal
Ensure the load current does not exceed 25A
Check available space on the DIN rail within your enclosure
Confirm the required contact logic (NO/NC) matches your application
Usage recommendations: Regularly inspect the terminal connections for tightness and ensure the device remains free of dust and moisture to maintain optimal performance. Periodically test the switching function during routine maintenance of the electrical installation.
