Hager CDA263J Residual Current Circuit Breaker 2P 63A 30mA Type A

The Hager CDA263J is a high-quality 2-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in modern installations. This device is designed to monitor electrical circuits and automatically disconnect power in the event of earth leakage currents, thereby protecting users from electric shock and preventing potential fire hazards. With a robust construction and reliable performance, it is a standard component for residential and commercial distribution boards.

Advantages

This residual current circuit breaker offers superior protection by detecting both alternating and pulsating direct residual currents, which is characteristic of Type A devices. Its 63A current rating and 30mA sensitivity make it highly effective for general-purpose protection in domestic and light commercial environments. The design focuses on durability and ease of installation, ensuring long-term operational stability and seamless integration into standard electrical panels.

Suitable for

• Residential electrical distribution boards
• Commercial office building circuits
• Protection of lighting and socket circuits
• Preventing electrical hazards in damp or high-risk areas

This device may not be suitable for industrial applications requiring higher current ratings or specialized protection against DC components beyond the scope of Type A specifications. It is also not intended for use in circuits where the total load consistently exceeds the 63A rated capacity.

Key specifications

• Number of poles: 2
• Rated current: 63A
• Residual current sensitivity: 30mA
• Device type: Type A
• Mounting type: DIN rail

To use the Hager CDA263J, it must be installed by a qualified electrician within a compatible distribution board. The device is mounted onto a standard DIN rail. Once installed, the circuit breaker should be tested periodically using the integrated test button to ensure the mechanical and electrical tripping mechanism remains fully functional.

What to consider before purchase

• Verify that the 63A rating is sufficient for your circuit load
• Ensure compatibility with existing DIN rail mounting systems
• Confirm that a Type A device meets your specific safety requirements
• Check local electrical regulations regarding the installation of RCCBs

Usage recommendations

Regularly press the test button at least every six months to verify that the device trips correctly, ensuring continued safety for your electrical installation.
