## Summary description

The Hager CDF640D is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety. It features a 40A rated current, 30mA sensitivity, and 10kA short-circuit capacity. As a Type F device, it is specifically engineered to detect AC and pulsating DC residual currents, making it ideal for protecting circuits with frequency converters or single-phase inverters in residential and commercial installations.

## Long description

The Hager CDF640D is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide reliable electrical protection in modern residential and commercial environments. With a rated current of 40A and a sensitivity of 30mA, this device is designed to detect leakage currents and disconnect the circuit instantly, preventing potential hazards. As a Type F device, it offers advanced protection by identifying both AC and pulsating DC residual currents, which are common in modern electronic equipment.
Advantages
The primary advantage of the Hager CDF640D is its specialized Type F technology, which ensures stability and safety in circuits containing frequency converters, single-phase inverters, and other power electronics. Unlike standard Type AC or A breakers, this unit is resistant to nuisance tripping caused by high-frequency interference, ensuring continuous operation of sensitive equipment. Its robust construction and 10kA short-circuit capacity provide long-term durability and high safety standards for complex electrical installations.
Suitable for
Circuits powering frequency converters and variable speed drives
Single-phase inverters in solar power systems
Heat pump installations and modern HVAC systems
Residential and commercial electrical distribution boards
When it may not be suitable
This device is not intended for use in circuits where only simple resistive loads are present, as a standard Type AC or Type A RCCB may be sufficient and more cost-effective. It is also not designed for high-voltage industrial applications exceeding its rated current and short-circuit capacity specifications.
Key specifications
Number of poles: 4
Rated current: 40A
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. It is typically mounted on a standard DIN rail within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and the load circuits to the output terminals, observing the correct polarity and torque settings as specified in the installation manual. After installation, the device should be tested using the integrated test button to verify its mechanical operation.
What to consider before purchase
Verify that the 40A rated current matches your circuit requirements
Ensure the 30mA sensitivity is appropriate for the intended level of personnel protection
Confirm that your installation includes equipment that requires Type F protection, such as inverters or frequency converters
Check the available space on the DIN rail within your distribution board
Usage recommendations
Regularly press the test button at least every six months to ensure the internal mechanism remains functional and the device trips as expected.
