## Summary description

Modular DIN-rail contactor FF ST25-20-24DC with two Z-type contacts designed for switching DC loads. Rated current 25 A and coil voltage 24 V DC. Intended for installation on standard DIN rails in control cabinets and distribution boards. Suitable for controlling motors, lighting circuits, and other DC equipment in industrial and commercial automation.

## Long description

Modular DIN-rail contactor FF ST25-20-24DC is a compact switching device designed for installation on standard DIN rails in control cabinets and distribution boards. It features two Z-type contacts and a 24 V DC coil, enabling reliable switching of DC loads up to a rated current of 25 A. The device is intended for use in industrial and commercial automation where space-efficient, modular control elements are required.
Advantages
The contactor provides a compact modular design for simple DIN-rail mounting and wiring, reducing installation time and panel space. Its two Z-type contacts allow flexible circuit configurations and improved switching reliability for DC applications. With a rated current of 25 A and a 24 V DC coil, the unit is suitable for a range of DC loads while offering stable operation and long service life when used within its electrical limits.
Suitable for
Switching DC motors and motor control circuits in small to medium automation systems
Control of DC lighting circuits and LED banks
Power switching in battery-backed and renewable energy systems
Integration into control cabinets for commercial or industrial equipment
Key specifications
Contact arrangement: 2 Z-type contacts (two switching poles)
Rated current: 25 A for DC switching
Coil voltage: 24 V DC
Mounting: standard DIN-rail (modular form factor)
Application: designed for switching DC loads in control panels and distribution boards
How to use
Mount the contactor on a standard DIN rail inside a suitably rated control cabinet or distribution board. Connect the DC supply to the coil terminals with 24 V DC, observing correct polarity and ensuring the supply meets the coil's voltage tolerance. Wire the DC load through the two Z-type switching contacts, verifying that the load current does not exceed 25 A. Follow local electrical codes and safety procedures during installation, including isolation of power before wiring and secure terminal tightening to manufacturer torque recommendations if provided.
Usage recommendations
For reliable long-term operation, ensure the contactor is used within its rated current and voltage limits, provide adequate overcurrent protection such as fuses or circuit breakers, and avoid frequent rapid cycling beyond the device specification. In applications with inductive loads, add appropriate suppression or snubber circuits to reduce electrical stress on contacts.
