Product information

Description

The Schneider A9Z05440 is a high-quality 4-pole residual current circuit breaker engineered to provide essential electrical safety in both residential and commercial environments. This device is specifically designed to detect and interrupt leakage currents, thereby protecting users from electric shocks and preventing potential fire hazards caused by insulation faults. By integrating this component into your electrical distribution board, you ensure a robust defense mechanism that maintains the integrity and safety of your entire electrical system.

Advantages

This residual current circuit breaker offers exceptional reliability and precision in fault detection. Its robust construction ensures long-term performance, while the 4-pole configuration allows for versatile application in three-phase electrical systems. The device is designed for seamless integration into standard electrical panels, providing a compact yet powerful solution for leakage protection that meets stringent safety standards.

Suitable for

  • Residential electrical distribution boards
  • Commercial building power systems
  • Protection of lighting and power circuits
  • Preventing fire hazards in electrical installations

When it may not be suitable

This device is designed for AC type leakage protection and may not be suitable for circuits where DC components or specific pulsating currents are present, as these may require different protection classes. It is also not intended for use in environments exceeding its rated current or voltage specifications.

Key specifications

  • Number of poles: 4P
  • Rated current: 40A
  • Sensitivity: 30mA
  • Voltage: 240V
  • Protection type: AC
  • Mounting: DIN rail

How to use

The device should be installed by a qualified electrician onto a standard DIN rail within an electrical distribution cabinet. Ensure that all wiring connections are tightened according to the manufacturer's torque specifications to prevent overheating. Once installed, the device can be tested using the integrated test button to verify that the tripping mechanism functions correctly. Regular testing is recommended to ensure ongoing protection.

What to consider before purchase

  • Verify that the 40A rating is sufficient for your circuit load
  • Ensure the 30mA sensitivity meets your specific safety requirements
  • Confirm compatibility with your existing DIN rail distribution board
  • Check the warranty terms for your specific user category

Usage recommendations

Regularly press the test button on the device at least every six months to confirm that the residual current protection mechanism remains operational and responsive to fault conditions.
