5. Installation and Wiring
The GYAR9-AC-G circuit breaker is designed for DIN rail mounting. Ensure all wiring is performed by a qualified professional in accordance with national and local electrical codes.
5.1. Mounting
- Ensure the power supply to the distribution box is completely disconnected.
- Attach the circuit breaker securely onto a standard 35mm DIN rail.
5.2. Wiring Diagram
Refer to the wiring diagram below for correct connection of the circuit breaker to the main power supply and loads. The diagram illustrates connections for the Line (L) and Neutral (N) inputs, as well as connections to multiple load circuits.

- Connect the main Line (L) and Neutral (N) wires to the designated terminals on the circuit breaker.
- Connect the load circuits to the output terminals.
- For manual control, an external normally open reset button can be connected to the auxiliary signal terminals (28-14 AWG, 1.5 mm²). The product does not require an external button for automatic reclosing.
- Ensure all connections are tight and properly insulated.
6. Operating Instructions
The GYAR9-AC-G offers both automatic and manual operating modes, selectable via a switch on the device.
6.1. Automatic/Manual Switching Modes
The device features an AUTO/MANU selector switch. The 'LOCK' mechanism prevents accidental operation when engaged.
- AUTO Mode: In this mode, the circuit breaker will automatically attempt to reclose after a fault trip. The digital display will show a red flashing light when the gate is open and a green flashing light when the gate is closing.
- MANU Mode: In this mode, the circuit breaker requires manual restoration after a fault trip. The yellow light on the display will remain on for manual opening and closing.
- LOCK Function: When the 'LOCK' switch is engaged (pulled out), the circuit breaker cannot be closed, ensuring electrical safety during maintenance or inspection and preventing accidental contact.

A table explains the automatic/manual switching and corresponding LED digital display behaviors.
6.2. Self-Locking Mode
To prevent continuous reclosing into a persistent fault, the device enters a self-locking mode after multiple consecutive trips:
- First Fault: The circuit breaker automatically recloses after 9 seconds.
- Second Fault: The circuit breaker automatically recloses after 59 seconds.
- Third Fault: The circuit breaker automatically recloses after 299 seconds.
- Fourth Fault: After the fourth consecutive fault, the recloser enters self-locking mode. Manual intervention is required. The circuit must be checked for safety, and then the gate must be manually reopened.
After 40 seconds of self-locking, the device will automatically recover and be ready for manual or automatic operation again, provided the fault has been cleared.

6.3. Digital Display Information
The 3-digit digital display provides critical operational feedback:
- Interruption Code: Displays a code indicating the type of interruption.
- Reclosing Count: Shows the number of times the circuit has been opened and reclosed.
- Countdown Timer: Indicates the remaining time until the next automatic reclosing attempt or recovery from self-locking mode.
- LED Indicator: Green for normal operation, red for MCB overcurrent error.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your circuit breaker.
- Visual Inspection: Periodically inspect the device for any signs of physical damage, discoloration, or loose connections.
- Cleaning: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Test Button: Press the 'Test Monthly' button (if available) regularly to verify the leakage protection function. Follow the instructions on the device for testing.
- Professional Check: Have a qualified electrician inspect the device and electrical system annually.
8. Troubleshooting
If the circuit breaker is not functioning as expected, consider the following:
- Device in Self-Locking Mode: If the device has tripped multiple times and is not reclosing, it may be in self-locking mode. Check the circuit for faults and manually reset the breaker.
- No Power: Verify the main power supply to the distribution box.
- Incorrect Mode: Ensure the AUTO/MANU switch is in the desired position. If in MANU mode, manual reset is required.
- Persistent Fault: If the breaker trips immediately after reclosing, there is a persistent fault in the circuit. Disconnect power and have a qualified electrician inspect the wiring and connected loads.
- Digital Display Error: Note any error codes displayed and consult a qualified electrician.
