## Summary description

Hager CDA225D residual-current device designed for electrical circuit protection against earth leakage faults. This 2-pole device features a rated current of 25 A, a sensitivity threshold of 30mA, and Type A protection characteristics. Occupying 2 modules in width, it is suitable for residential and commercial electrical distribution boards, ensuring safety against electrical shock and fire hazards.

## Long description

The Hager CDA225D Residual-Current Device is a reliable 2-pole electrical safety component designed to protect electrical circuits against earth leakage faults. Operating with a rated current of 25 A and a sensitivity threshold of 30mA, this Type A device effectively detects both sinusoidal AC and pulsating DC residual currents. It occupies 2 modules in width and is engineered for seamless integration into standard residential and commercial electrical distribution boards, providing essential safety against electric shock and electrical fire hazards.
Advantages
This residual-current device delivers dependable circuit protection by quickly disconnecting power when earth leakage is detected, significantly reducing the risk of direct and indirect contact shocks. Built to high manufacturing standards by Hager, it ensures long-term operational stability and safety within electrical installations. Its Type A characteristic makes it versatile for modern electronic equipment with pulsating components. The compact 2-module width optimizes space within the distribution board while maintaining high performance and easy installation for qualified professionals.
Suitable for
Residential electrical distribution boards for personal shock protection
Commercial office buildings and retail spaces circuit safety
Protecting circuits connected to electronic devices with pulsating DC components
Preventing electrical fires caused by insulation failures and earth leakage
When it may not be suitable
This device is not suitable for three-phase electrical systems as it is specifically designed for 2-pole single-phase applications. Additionally, it should not be used in environments requiring Type B RCDs, which are necessary for complex smooth DC residual currents found in certain industrial setups or specific EV charging applications.
Key specifications
Rated current: 25 A
Number of poles: 2-pole
Sensitivity threshold: 30mA
Protection type: Type A
Module width: 2 modules
How to use
The Hager CDA225D must be installed exclusively by a qualified and licensed electrician in accordance with local electrical regulations and wiring standards. It is mounted onto a standard DIN rail inside an electrical distribution board or consumer unit. Ensure the power supply is completely switched off before beginning installation. Connect the incoming and outgoing phase and neutral conductors to the corresponding terminals, ensuring proper torque is applied to the screw connections to prevent loose contacts. After installation, test the device using the integrated test button to verify correct mechanical and electrical operation.
What to consider before purchase
Verify that the 25 A rated current matches the specific electrical load requirements of your circuit
Confirm that your distribution board has sufficient physical space, requiring 2 standard module widths
Ensure a Type A residual-current device meets the regulatory and technical demands of your installation
Check that the application is single-phase, as this is a 2-pole device
Regularly test the residual-current device using the built-in test button every six months to ensure proper functioning and reliable protection against electrical hazards.
