## Summary description

Modular contactor FF ST25-20 is a DIN-rail mount switching device rated for 25 A with two normally open (2NO) main contacts and a 230 V AC coil. Designed for control and automation circuits, it suits lighting, heating, and motor control switching in residential and commercial electrical installations where compact modular switching is required.

## Long description

Modular Contactor FF ST25-20 25A 2NO 230V AC is a DIN-rail mounted switching device designed for compact control and automation circuits. It provides two normally open (2NO) main contacts rated for continuous switching at up to 25 A and is actuated by a 230 V AC coil. The slim modular form factor fits standard distribution boards and allows straightforward integration into lighting, heating, and motor control systems in both residential and light commercial installations.
Advantages
The modular design saves panel space and enables easy mounting on standard DIN rails. Two normally open contacts allow independent switching of two circuits or two-pole control of single-phase loads. The 25 A contact rating supports a range of lighting, heating, and small motor applications while the 230 V AC coil matches common control voltages in electrical installations. The device offers reliable electromechanical switching with clear physical separation between control and load circuits.
Suitable for
DIN-rail installation in residential and commercial distribution boards
Switching of lighting circuits and lighting groups
Control of heating elements and electric radiators
Start/stop control for small motors and pumps within rated current
Integration into automation panels and control cabinets
Key specifications
Contact configuration: 2 normally open (2NO) main contacts
Rated current: 25 A for main contacts
Control coil voltage: 230 V AC
Mounting: standard DIN-rail (TS35) modular enclosure
Device type: electromechanical modular contactor for switching loads
How to use
Mount the contactor on a standard DIN-rail inside the distribution board or control cabinet. Connect load conductors to the main contact terminals and the supply to the coil terminals according to the wiring diagram supplied with the installation materials. Ensure the coil is energized with 230 V AC and check that the connected loads do not exceed the 25 A rating per contact. Secure wiring with appropriate ferrules or terminals and follow local electrical codes for protective devices and conductor sizing.
Usage recommendations
Use appropriate overcurrent protection and consider contactor grouping when switching inductive loads; allow for inrush currents of motors and transformers. For frequent switching applications, verify thermal endurance and consult load duty cycles. Ensure correct coil voltage and provide isolation during maintenance.
