Hager CDA216J Residual Current Circuit Breaker 2P 16A 30mA Type A

The Hager CDA216J is a high-quality 2-pole residual current circuit breaker (RCCB) engineered to provide reliable electrical safety in residential and commercial environments. This device is designed to monitor electrical circuits and automatically disconnect power when a residual current is detected, effectively preventing electric shocks and mitigating the risk of fire caused by insulation faults. As a Type A device, it offers comprehensive protection by detecting both standard AC residual currents and pulsating DC residual currents, making it a versatile choice for modern electrical installations.

Advantages

The primary advantage of this Hager RCCB is its robust construction and high sensitivity, which ensures rapid response times during fault conditions. By utilizing Type A technology, the device provides enhanced safety for circuits that include electronic components, such as LED drivers, dimmers, or household appliances with power electronics. Its compact design allows for efficient installation within standard distribution boards, while the durable materials ensure long-term operational stability and consistent performance under various load conditions.

Suitable for

• Residential electrical distribution boards
• Commercial office building circuits
• Protection of circuits with electronic power supplies
• General purpose electrical safety in indoor environments

When it may not be suitable

This device is not intended for use in circuits requiring Type B protection, which is necessary for specific industrial applications involving frequency converters or complex DC power systems. It is also not suitable for outdoor environments unless installed within a properly rated, weather-protected enclosure.

Key specifications

• Number of poles: 2
• Rated current: 16A
• Residual current sensitivity: 30mA
• Type: A
• Mounting type: DIN rail

How to use

The Hager CDA216J must be installed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting on a standard DIN rail within a consumer unit or distribution board. Ensure that the supply cables are correctly connected to the input terminals and the load cables to the output terminals, observing the correct polarity and torque settings as specified by the manufacturer. Once installed, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.

What to consider before purchase

• Verify that the 16A rating is appropriate for your circuit load
• Ensure the 30mA sensitivity meets local safety standards for your specific application
• Check that your distribution board has sufficient space for a 2-pole module
• Confirm that Type A protection is required for your specific electrical equipment

Usage recommendations

Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the mechanism remains operational and provides continuous protection for your electrical system.
