## Long description

The F&F ST25-11 modular contactor is a high-quality electromechanical switching device engineered for the reliable control of electrical circuits in various environments. Designed for seamless integration into standard electrical distribution boards, this unit operates with a rated current of 25A and a coil voltage of 230V AC. 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 durability and consistent performance in both residential and industrial applications. Its compact design allows for efficient space utilization on standard DIN rails, simplifying the installation process within electrical cabinets. The robust construction ensures long-term reliability for frequent switching operations, while the clear contact configuration provides flexibility for diverse control logic requirements in modern electrical installations.
Suitable for
Lighting control systems
Heating and cooling equipment

Automated power distribution circuits
Industrial machinery control
This device may not be suitable for applications requiring higher current ratings exceeding 25A or for environments with extreme vibration or high levels of dust and moisture without an appropriate protective enclosure. It is intended for use in standard AC circuits and should not be used in DC applications unless specifically rated for such use.
Key specifications
Rated current: 25A
Coil voltage: 230V AC
Contact configuration: 1 normally open (NO) and 1 normally closed (NC)
Mounting type: DIN rail
Design: Modular
To install the contactor, mount it securely onto a standard 35mm DIN rail within a distribution board. Ensure that the power supply is disconnected before making any electrical connections. Connect the control wires to the coil terminals and the load wires to the appropriate NO or NC power terminals according to the wiring diagram. Once installed, verify that all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 25A rated current is sufficient for your specific load requirements.
Ensure the 230V AC coil voltage matches your control circuit voltage.
Check the available space on your DIN rail to accommodate the modular width.
Confirm that the 1NO and 1NC contact configuration meets your control logic needs.
Usage recommendations
Always ensure that the electrical installation is performed by a qualified professional in accordance with local safety regulations and standards. Regularly inspect the contactor for signs of wear or loose connections to maintain optimal system performance.
