## Long description

The Hager ESD425SDC is a high-performance silent modular contactor engineered for efficient electrical switching within distribution boards. With a 25A current rating and four normally open (4NO) contacts, this device provides reliable control for various electrical circuits. It is specifically designed to operate on a 24V AC/DC control voltage, ensuring versatility in diverse automation and power management setups. The silent operation feature makes it an excellent choice for environments where acoustic comfort is a priority, such as residential buildings, offices, and hospitals.
Advantages
The primary benefit of the Hager ESD425SDC is its silent switching mechanism, which eliminates the audible hum typically associated with standard contactors. This makes it ideal for installation in living spaces or quiet professional areas. Its modular design allows for seamless integration into standard DIN rail distribution boards, simplifying the installation process. Furthermore, the dual AC/DC control voltage capability provides flexibility for different control system architectures, while the robust construction ensures long-term durability and consistent performance under regular load conditions.
Suitable for
Residential lighting control systems
Heating and ventilation management in quiet zones
Commercial building automation
Switching of small motors and pumps
General electrical load management in distribution boards
When it may not be suitable
This contactor is not intended for high-power industrial applications that exceed its 25A current rating or 400V operational voltage limit. It is also not suitable for environments requiring specialized explosion-proof equipment or extreme outdoor conditions without appropriate protective enclosures.
Key specifications
Rated current: 25A
Contact configuration: 4 normally open (4NO)
Control voltage: 24V AC/DC
Operational voltage: 400V AC
Mounting type: DIN rail
How to use
The Hager ESD425SDC should be installed by a qualified electrician in accordance with local electrical regulations. The device is designed to be snapped onto a standard 35mm DIN rail within a distribution board. Connect the control circuit wires to the A1 and A2 terminals, ensuring the 24V AC/DC supply is correctly matched. The load circuits should be connected to the main power terminals. Before finalizing the installation, verify that all connections are secure and that the wiring matches the intended circuit diagram.
What to consider before purchase
Verify that your control system provides a 24V AC/DC signal.
Ensure the total load current does not exceed 25A.
Check the available space in your distribution board for modular components.
Confirm that the 4NO contact configuration meets your specific switching requirements.
Usage recommendations
For optimal performance and longevity, ensure the contactor is installed in a well-ventilated distribution board to prevent excessive heat buildup. Regularly inspect the terminal connections for tightness during routine maintenance to avoid overheating or poor contact.
