Hager CDF625D Residual Current Circuit Breaker 4P 25A 30mA 10kA Type F

The Hager CDF625D is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide advanced electrical safety in modern installations. Designed to handle a rated current of 25A and featuring a 30mA sensitivity threshold, this device is essential for protecting circuits against leakage currents. With a robust 10kA short-circuit capacity, it ensures reliable operation even under demanding electrical conditions. As a Type F device, it is specifically optimized for circuits containing frequency converters, offering superior protection against electric shock and fire risks compared to standard AC or A-type breakers.

Advantages

The primary advantage of the Hager CDF625D lies in its specialized Type F technology, which allows it to detect complex residual currents, including those with mixed frequencies often generated by modern electronic equipment. This makes it an ideal choice for installations involving variable speed drives and frequency converters. The device is built to high manufacturing standards, ensuring long-term durability and consistent performance in both residential and commercial environments. Its 4-pole configuration provides comprehensive protection across all phases, enhancing the overall safety profile of the electrical distribution system.

Suitable for

• Circuits powering frequency converters and variable speed drives
• Residential electrical panels requiring enhanced protection for modern appliances
• Commercial installations with sensitive electronic equipment
• Systems where protection against pulsating DC and mixed frequency leakage is required

This device may not be suitable for standard AC-only circuits where a more basic and cost-effective Type AC or Type A breaker would suffice, as the specialized Type F functionality is specifically intended for complex electronic loads. It is also not designed for high-current industrial applications exceeding its 25A rating.

Key specifications

• Number of poles: 4
• Rated current: 25A
• Sensitivity: 30mA
• Short-circuit capacity: 10kA
• Type: F

Installation of the Hager CDF625D must be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a distribution board. Ensure that the supply voltage and load requirements are compatible with the breaker's specifications before connection. Once installed, the integrated test button should be used to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify that the 25A rated current matches your circuit load requirements
• Ensure the 30mA sensitivity is appropriate for the intended level of personnel protection
• Confirm that the installation environment requires Type F protection for frequency converter compatibility
• Check the available space on the DIN rail within your distribution board

For optimal safety, it is recommended to perform a functional test of the residual current circuit breaker using the test button at least every six months to ensure the device remains in good working order.
