## Long description

The Hager Residual Current Circuit Breaker CDS240R 1P+N 40A 30mA Type A is designed to protect electrical installations against insulation faults, earth leakage currents, and potential electric shocks. This modular residual current device ensures safety in both residential and commercial electrical systems by automatically disconnecting the circuit when a residual current is detected.
Advantages
This residual current circuit breaker provides reliable fault current detection for modern electrical grids. The Type A designation ensures sensitivity to both alternating sinusoidal residual currents and pulsating direct residual currents, which are commonly generated by electronic devices and appliances. Built to high manufacturing standards by Hager, the device guarantees dependable everyday operation, helps prevent electrical hazards, and contributes to overall electrical system safety.
Suitable for
Residential electrical distribution boards and consumer units
Commercial building sub-distribution circuits
Protecting lighting and socket circuits against direct and indirect contact
Safeguarding standard household appliances and office equipment
When it may not be suitable, this device is not designed for standalone overload or short-circuit protection and must always be paired with an appropriate miniature circuit breaker or fuse. Additionally, it is not intended for heavy industrial DC networks requiring Type B protection without proper intermediate conversion.
Key specifications
Pole configuration: 1P+N (1 protected pole plus switched neutral)
Rated current: 40 Amperes
Residual operating current sensitivity: 30 milliamperes
Residual current protection type: Type A
To use the Hager CDS240R, it must be installed by a qualified electrician within a standard distribution board or consumer unit on a DIN rail. Ensure the power supply is completely switched off before mounting or wiring the device. Connect the incoming and outgoing line and neutral conductors securely to the designated terminals, paying close attention to the indicated polarity and tightening torque specifications. Regularly test the mechanical tripping function using the integrated test button.
What to consider before purchase includes verifying your main electrical system load requirements to ensure the 40 Ampere rating matches your circuit capacity. Check that a 30 milliampere sensitivity threshold is appropriate for your specific application, as it provides standard personnel protection. Confirm physical space availability on your distribution board DIN rail and ensure compatibility with existing miniature circuit breakers.
For optimal safety and reliable performance, test the residual current circuit breaker manually using the test button at least twice a year. Always ensure that installation and maintenance work is performed in compliance with local electrical regulations and carried out by a certified professional.
