Product information

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.
