Product information

Description

The Hager CDF640D is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide advanced electrical safety in both residential and commercial environments. This device is specifically designed to detect and interrupt leakage currents, protecting users from electric shock and preventing potential fire hazards caused by insulation faults. With a rated current of 40A and a sensitivity of 30mA, it ensures rapid response to hazardous conditions, while its 10kA short-circuit capacity offers robust protection against high-energy electrical faults.

As a Type F device, the Hager CDF640D is superior to standard Type AC or A breakers because it is specifically designed to handle complex electronic loads. It provides reliable protection against both alternating residual currents and pulsating DC residual currents, as well as mixed frequency currents that are common in modern electrical installations. This makes it an essential component for maintaining safety in systems that utilize sophisticated power electronics.

Advantages

The primary advantage of this RCCB is its Type F classification, which ensures stability and reliability in circuits containing frequency converters, variable speed drives, and other modern electronic equipment that can cause nuisance tripping in standard devices. Its 4-pole configuration allows for versatile application in three-phase systems, providing comprehensive coverage for all phases and the neutral conductor. The robust construction and 10kA breaking capacity ensure that the device remains operational and effective even under demanding electrical conditions, offering long-term durability and peace of mind for electrical installers and end-users alike.

Suitable for

  • Circuits equipped with frequency converters and variable speed drives
  • Residential installations with modern heat pumps or air conditioning systems
  • Commercial buildings utilizing complex electronic power supplies
  • Protection of electrical circuits with high-frequency interference
  • General electrical safety in three-phase distribution boards

When it may not be suitable

This device is not intended for use in DC-only electrical systems or circuits where pure DC leakage currents are present, as it is designed for AC and pulsating DC components. It should not be installed in environments exceeding its specified temperature or environmental ratings, as this may affect its tripping accuracy and mechanical longevity.

Key specifications

  • Number of poles: 4
  • Rated current: 40A
  • Residual current sensitivity: 30mA
  • Short-circuit capacity: 10kA
  • Type: F

How to use

The Hager CDF640D must be installed by a qualified electrician in accordance with local electrical regulations and standards. It is designed for mounting on a standard DIN rail within a distribution board. Before installation, ensure that the power supply is disconnected. The device should be wired according to the terminal markings, ensuring that all phase conductors and the neutral conductor are correctly connected. Once installed, the integrated test button should be pressed to verify the mechanical functionality of the tripping mechanism. Regular testing is recommended to ensure the device remains in optimal working condition.

What to consider before purchase

  • Verify that the 40A rated current is sufficient for the total load of the circuit
  • Ensure the 30mA sensitivity meets the safety requirements for your specific application
  • Confirm that the installation environment is compatible with a Type F RCCB
  • Check the available space on your DIN rail within the distribution cabinet

Usage recommendations

Regularly test the device using the built-in test button at least every six months to ensure the tripping mechanism remains functional and free from debris or mechanical binding.
