Product information

Description

The Hager CDB663D is a 4-module residual-current device designed to provide reliable protection against earth leakage and certain types of fault currents. With a rated current of 63 A and a breaking capacity of 800 A, this Type B+ RCD is built for installations that require sensitivity to both AC and smooth DC fault components. Its compact housing (72 mm wide, 70 mm deep, 85 mm high) fits standard distribution boards and minimizes space consumption while operating at the standard mains frequency of 50 Hz and a total power loss of 9.29 W.

Advantages

The device offers selective protection for circuits where both AC and pulsating or smooth DC leakage currents may occur, reducing the risk of undetected faults. Its 63 A rated current and 800 A breaking capacity provide secure disconnection under fault conditions, while the Type B+ characteristic increases compatibility with modern equipment and power electronic loads. The compact 4-module form factor and modest power loss make it suitable for retrofit and new installations where panel space and thermal performance are considerations.

Suitable for

Residential and commercial electrical distribution panels
Circuit protection with mixed loads including power electronics and variable-speed drives
Applications requiring detection of AC, pulsating DC and smooth DC residual currents
Installation where compact 4-module devices are needed

How to use

Install the Hager CDB663D in a suitable distribution board according to applicable electrical codes and wiring diagrams. Ensure connections are made to appropriate line and neutral terminals with correct torque settings and that upstream protective devices are coordinated. Verify that the device rating (63 A) and breaking capacity (800 A) are compatible with the connected circuits. After installation, perform standard commissioning tests to confirm correct operation and residual-current sensitivity before placing the circuit into service.

Usage recommendations

For safe and compliant operation, have installation and testing performed by a qualified electrician. Coordinate the RCD with upstream and downstream protective devices, and routinely test the device per local regulations to ensure continued sensitivity to leakage currents.
