Hager CDS463D Residual-Current Device Type A 63 A 230 V 4 Modules

The Hager CDS463D Residual-Current Device Type A 63 A 230 V 4 Modules is an essential electrical safety component designed to protect circuits and users from electrical shocks and fault currents. Manufactured by Hager, this 4-pole device operates with a rated current of 63 A and a rated voltage of 230 V, taking up 4 module spaces in an electrical enclosure. It utilizes Type A residual current detection to safely monitor and disconnect power when earth leakage currents are detected, ensuring stable and secure power distribution.

Advantages

This residual-current device provides reliable circuit protection by quickly disconnecting power in the event of earth faults, significantly reducing the risk of electric shock. Its Type A classification ensures accurate detection of both sinusoidal AC and pulsating DC residual currents, making it versatile for modern electrical environments. Featuring QuickConnect terminals, the installation process is streamlined and efficient, allowing for secure connections without unnecessary delays. Built to high manufacturing standards, it contributes to long-term electrical safety and system stability in both residential and commercial buildings.

Suitable for

• Residential electrical installations and consumer units
• Commercial building power distribution boards
• Protection against electric shocks from direct and indirect contact
• Safeguarding circuits with electronic equipment sensitive to pulsating DC currents

When it may not be suitable

This device may not be suitable for specialized industrial installations requiring Type B residual-current protection for smooth DC leakage currents. It is also not designed for systems operating outside its specified rated voltage and current parameters, such as higher voltage industrial machinery or lower amperage dedicated control circuits.

How to use

The Hager CDS463D should be installed exclusively by a qualified electrician within a compatible electrical distribution board or consumer unit. Ensure the main power supply is fully disconnected before beginning any installation work. Mount the 4-module device onto the standard DIN rail inside the enclosure and connect the line and neutral conductors to the designated terminals using the QuickConnect system. After installation, verify proper operation by pressing the integrated test button to ensure the mechanism trips correctly.

What to consider before purchase

• Verify that the 63 A rated current and 230 V rating match your electrical system requirements
• Ensure there is sufficient physical space of 4 modules available in your distribution board
• Check if Type A residual current protection meets the regulatory standards for your specific application
• Confirm installation by a certified professional to maintain safety and compliance

Usage recommendations: Regularly test the residual-current device by pressing the test button at least once every six months to ensure proper mechanical and electrical operation. If the device fails to trip during testing or frequently trips under normal load conditions, consult a qualified electrician immediately for inspection and troubleshooting.
