FAQs

What is the difference between 30mA and 300mA protection?

The 30mA setting is for enhanced personal protection against direct electric shock, typically used in areas with increased risk like bathrooms. The 300mA setting is for protection against indirect contact and fire risk, suitable for general building installations.

How often should I test the ACTI 9 iDPN Vigi?

It is recommended to test the breaker monthly using the test button to ensure its proper functioning. Always follow local electrical codes and manufacturer recommendations for testing frequency.

Can I use this breaker with any electrical system?

The ACTI 9 IC40 is designed for standard AC electrical systems within its voltage and current ratings. While it mounts on a standard DIN rail, ensure compatibility with your specific panel and wiring standards.

What does '1p+n' mean?

'1p+n' means the breaker has two poles: one for the phase conductor and one for the neutral conductor. Both poles are switched simultaneously, providing complete isolation.

What happens if the power goes out and then comes back on?

The ACTI 9 iDPN Vigi is designed to remain in its current state (on or off) when power is interrupted. It will not automatically re-close upon restoration of power, ensuring safety.

Is this breaker suitable for outdoor use?

This device is intended for use within electrical enclosures that provide adequate protection against environmental factors like moisture and dust. Ensure the installation environment meets the required IP rating.

Troubleshooting

Breaker trips immediately upon power restoration

This indicates a persistent ground fault or a short circuit in the connected wiring or appliance. Disconnect all loads and test the breaker with no load connected. If it still trips, the breaker may be faulty. If it doesn't trip, reconnect loads one by one to identify the faulty circuit or device.

Test button does not trip the breaker

The internal mechanism of the ground fault detection may be compromised. Ensure the circuit is energized. If the issue persists, the breaker may need replacement.

Breaker does not trip under load fault conditions

Verify that the circuit is properly wired and energized. Test the breaker using the test button. If the test function works but load faults do not trip it, there might be an issue with the wiring or the nature of the fault. If the test button also fails, the unit likely needs replacement.

Red ground fault indicator is constantly active

This indicates a continuous ground fault condition in the protected circuit. Investigate connected appliances and wiring for faults. If no immediate fault is found, consider temporarily isolating sections of the circuit to pinpoint the source.

Pros and Cons

Pros

  • Provides robust protection against electrical shocks and fire hazards.
  • Features a quick and straightforward installation process.
  • Clear visual indicators for pole status and ground faults.
  • Safety features like padlock locking enhance maintenance security.
  • Operates independently of voltage for continuous protection.

Cons

  • Requires a basic understanding of electrical wiring for safe installation.
  • Specific to Schneider Electric's ACTI 9 system, limiting broad compatibility with other brands.
  • As a safety device, requires regular testing to ensure functionality.

Setup, Compatibility & Care

Setup:

  1. Ensure the main power supply is turned off before installation.
  2. Mount the ACTI 9 iDPN Vigi breaker onto a standard DIN rail in your electrical panel.
  3. Connect the phase and neutral conductors to the designated terminals according to local electrical codes and the device's wiring diagram.
  4. Ensure secure connections to prevent loose wiring.
  5. Re-energize the main power supply and test the breaker using the integrated test button.

Compatibility:

The ACTI 9 IC40 series is designed to work seamlessly within the Schneider Electric ACTI 9 modular system. While it adheres to standard DIN rail mounting, specific interconnectivity and busbar systems may be proprietary. It is compatible with standard electrical wiring and grounding systems.

Care:

  • Regularly test the device using the built-in test button (recommended monthly or as per local regulations).
  • Keep the breaker and surrounding electrical panel clean and free from dust and moisture.
  • Visually inspect the device for any signs of damage or overheating.
