Product information

Description

The Hager CDA440D residual current circuit breaker is designed to provide reliable electrical protection in residential and commercial power distribution installations. Featuring a Type A design with a 4-pole configuration and a 40 A rated current, this device is engineered to handle input voltages of 230/400 V and a coil voltage of 500 V. It effectively safeguards electrical circuits and users by quickly disconnecting the power supply when residual currents are detected.

Advantages

This residual current circuit breaker offers dependable safety for various electrical setups by instantly interrupting fault currents. Its Type A classification ensures accurate detection of both sinusoidal AC residual currents and pulsating DC residual currents. The 4-pole configuration makes it suitable for comprehensive multi-phase distribution networks, while the robust Hager construction guarantees long-term operational stability and safety compliance.

Suitable for

  • Residential electrical distribution boards
  • Commercial building power systems
  • Multi-phase electrical installations requiring Type A protection
  • Sub-distribution boards for enhanced circuit safety

When it may not be suitable

This device is not designed for single-phase circuits that require only a 2-pole configuration. Additionally, it may not be appropriate for specialized industrial applications requiring Type B residual current devices that detect smooth DC residual currents.

Key specifications

  • Type A residual current circuit breaker
  • 4-pole configuration
  • 40 A rated current
  • Input voltages of 230/400 V
  • Coil voltage of 500 V

How to use

The device must be installed exclusively by a qualified electrician in compliance with current electrical safety regulations and wiring standards. It is mounted onto a standard DIN rail within a distribution enclosure. Ensure the power supply is completely switched off before installation, wiring, or performing any maintenance work on the electrical panel.

What to consider before purchase

  • Verify that your electrical system requires a 4-pole, 40 A device
  • Check if Type A residual current protection matches your specific installation requirements
  • Ensure compatibility with your existing distribution board and DIN rail mounting space

Usage recommendations

Test the residual current circuit breaker periodically using the integrated test button to ensure correct mechanical and electrical functionality. Regular inspections help maintain optimal safety levels in your power distribution network.
