Product information

Description

The Hager CDS425D is a professional-grade residual current circuit breaker (RCCB) engineered to provide superior electrical protection in both residential and commercial environments. This 4-pole device is designed to monitor electrical circuits and automatically disconnect power when a residual current is detected, thereby preventing potential hazards such as electric shocks or fire risks. With its robust construction and advanced Type A sensitivity, it ensures reliable performance by detecting both alternating current (AC) and pulsating direct current (DC) residual currents, making it a versatile choice for modern electrical systems.

Advantages

The primary benefit of this RCCB is its integration of QuickConnect technology, which significantly simplifies the installation process by allowing for faster and more secure wire connections without the need for traditional screw terminals. Its Type A classification provides a higher level of safety compared to standard AC-type breakers, as it remains effective in circuits containing electronic components that may produce pulsating DC currents. The compact 4-module design ensures it fits seamlessly into standard distribution boards, optimizing space while maintaining high safety standards.

Suitable for

  • Residential electrical distribution boards
  • Commercial office building power circuits
  • Protection of circuits with electronic equipment like LED drivers or induction hobs
  • General electrical safety in buildings requiring Type A protection

When it may not be suitable

This device is not intended for use in circuits where the load exceeds the 25A rated current, as this could lead to nuisance tripping or damage to the unit. It is also not a substitute for a miniature circuit breaker (MCB) and must be used in conjunction with appropriate overcurrent protection devices.

Key specifications

  • Rated current: 25A
  • Sensitivity: 30mA
  • Type: A
  • Number of poles: 4 (3P+N)
  • Mounting: DIN rail (4 modules)
  • Operating voltage: 230V/400V

How to use

The Hager CDS425D should be installed by a qualified electrician within a standard distribution board on a DIN rail. Ensure that the supply cables are correctly connected to the input terminals and the load cables to the output terminals using the QuickConnect system. Once installed, the device should be tested using the integrated test button to verify that the tripping mechanism functions correctly before the circuit is put into regular operation.

What to consider before purchase

  • Verify that the 25A rating is sufficient for your specific circuit load
  • Ensure your distribution board has 4 modules of available space
  • Confirm that Type A protection is required for your specific appliances
  • Check local electrical regulations regarding the installation of residual current devices

Usage recommendations

Regularly test the device using the test button at least every six months to ensure the mechanical tripping function remains operational and reliable.
