FAQs

What is the main difference between an RCBO and an RCD?

An RCD (Residual Current Device) only provides protection against earth leakage faults. An RCBO (Residual Current Breaker with Overcurrent protection) combines the functions of an RCD and an MCB (Miniature Circuit Breaker), providing protection against both earth leakage and overcurrents (overloads and short circuits) in a single device.

What does '30mA Type A' earth leakage sensitivity mean?

30mA is the residual current level at which the device will trip, providing protection against electric shock. 'Type A' indicates that it can detect both AC and pulsating DC residual currents, offering broader protection than Type AC devices.

Can this RCBO be used for single-phase circuits?

This is a 3-pole RCBO, typically used for three-phase applications. While it can be adapted for certain single-phase systems by only using one pole and leaving the others blank, it is generally recommended to use a 1-pole or 2-pole RCBO for standard single-phase circuits to optimize space and cost.

What is the breaking capacity of this RCBO?

The Schneider Electric iC60 RCBO A9D17332 has a breaking capacity of 10kA at 220-240VAC according to EN/IEC 61009-2-1, and 15kA according to EN/IEC 60947-2.

How do I perform a test on the RCBO?

Most RCBOs have a 'Test' button. With the circuit energized, press the test button. The RCBO should trip. This test verifies the functionality of the residual current detection mechanism. It is recommended to perform this test periodically as per local regulations.

What is the operating temperature range?

The operating temperature range for this RCBO is -25°C to 40°C.

Is this product compliant with international standards?

Yes, this RCBO is designed and tested according to EN/IEC 61009-2-1 and EN/IEC 60947-2 standards.

Troubleshooting

RCBO trips immediately upon reset

This indicates a persistent fault on the circuit. Check for short circuits or severe earth leakage. If the fault cannot be identified, disconnect all loads and test incrementally, or consult a qualified electrician.

Nuisance tripping (occasional, unexplained trips)

This could be due to temporary current surges from connected equipment (especially with Type C curve). Ensure the circuit is not overloaded and that the trip curve is appropriate for the connected loads. Consider if the 30mA sensitivity is suitable for the application or if a higher sensitivity is needed for sensitive equipment.

RCBO does not reset

Ensure the circuit is de-energized and free from faults. If the unit appears damaged or will not reset after confirming no fault, it may need replacement. Professional inspection is advised.

No earth leakage protection (no trip on test button)

If the RCBO passes overcurrent tests but fails the earth leakage test, the residual current detection module may be faulty. This requires professional diagnosis and potential replacement.

Pros and Cons

Pros

  • Provides dual protection (overcurrent and earth leakage) in one device.
  • High breaking capacity ensures safety during fault conditions.
  • Type A sensitivity offers protection against a wider range of fault currents.
  • Durable with a long operational lifespan.
  • Compact design saves space in electrical panels.

Cons

  • Requires professional installation due to its electrical nature.
  • Specific sensitivity type (Type A) might not be suitable for all unique applications.
  • 3-pole configuration may be overkill for single-phase systems.
  • Limited to 220-240VAC operating voltage.
  • Package weight can be a consideration for large quantities.

Setup, Compatibility & Care

Setup:

Installation of the iC60 RCBO must be performed by a qualified electrician in accordance with local wiring regulations and codes. Ensure the main power supply is disconnected before commencing any work.

  1. Mounting: The RCBO is designed for DIN rail mounting within an appropriate electrical enclosure.
  2. Wiring: Connect the incoming power supply to the line terminals and outgoing circuits to the load terminals. For a 3-pole unit, ensure all three live conductors are connected correctly to the corresponding terminals.
  3. Connection: Ensure all connections are secure and properly insulated.

Compatibility:

  • Voltage: Operates at 220-240VAC.
  • Frequency: Designed for 50Hz systems.
  • Enclosure: Should be installed in an enclosure providing at least IP20 protection.

Care:

  • Routine Testing: It is recommended to periodically test the earth leakage function by pressing the 'Test' button (if applicable and integrated). Consult local regulations for testing frequency.
  • Cleaning: Keep the RCBO and its enclosure clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents or abrasive materials.
  • Inspection: Visually inspect the unit and connections periodically for any signs of damage or overheating.
