Hager ADC810H Residual Current Circuit Breaker with Overcurrent Protection (RCBO) User Manual

1. Introdução

The Hager ADC810H is a compact and reliable Residual Current Circuit Breaker with Overcurrent Protection (RCBO), designed for the protection of electrical installations against both overcurrents (overload and short-circuit) and earth leakage currents. This device is a bipolar 1P+N unit, suitable for single-phase systems, ensuring enhanced safety and operational flexibility. Its design facilitates easy installation in industrial and domestic environments, providing precise monitoring of differential currents.

2. Instruções de segurança

WARNING: Electrical work should only be performed by qualified and authorized personnel. Failure to follow these instructions can result in serious injury or death.

• Always disconnect the main power supply before installing, maintaining, or troubleshooting the device.
• Assegure-se de que o sistema elétrico esteja devidamente aterrado.
• Verify that the device ratings (voltage, current, breaking capacity) match the requirements of your electrical installation.
• Não utilize o aparelho se ele apresentar sinais de danos.
• Regularly test the residual current function using the test button.

3. Produto acabadoview

The Hager ADC810H RCBO integrates both overcurrent and residual current protection in a single compact unit. It features a robust housing and clear markings for easy identification and connection.

Esta imagem mostra a frente view of the Hager ADC810H Residual Current Circuit Breaker with Overcurrent Protection (RCBO). Visible are the toggle switch for manual operation, the test button, and the connection terminals for phase and neutral conductors.

Os principais componentes incluem:

• Interruptor: For manual ON/OFF operation and indication of trip status.
• Botão de teste: Used to periodically test the residual current tripping mechanism.
• Terminais de conexão: Clearly marked for phase (L) and neutral (N) input and output.
• Clipe de montagem para trilho DIN: For secure installation on a DIN rail.

4. Instalação

The Hager ADC810H RCBO is designed for DIN rail mounting. Follow these steps for safe and correct installation:

1. Desconexão de energia: Ensure the main power supply to the installation is completely disconnected and secured against accidental re-connection.
2. Montagem: Clip the RCBO onto the DIN rail in the consumer unit or distribution board. Ensure it is securely seated.
3. Wiring - Input: Connect the incoming phase (L) and neutral (N) conductors to the upper terminals of the RCBO. Ensure correct polarity and tight connections.
4. Wiring - Output: Connect the outgoing phase (L) and neutral (N) conductors to the lower terminals of the RCBO, leading to the protected circuit. Ensure correct polarity and tight connections.
5. Torque: Tighten all terminal screws to the manufacturer's specified torque to prevent loose connections and overheating.
6. Verificação: Verifique novamente se todas as conexões estão corretas e seguras antes de religar a energia.

5. Operação

The RCBO operates automatically to protect against electrical faults. Manual operation is also possible:

• Ligando: Push the toggle switch upwards to the 'ON' position.
• Desligando: Push the toggle switch downwards to the 'OFF' position.
• Disparo automático: In the event of an overcurrent (overload or short-circuit) or an earth leakage current exceeding 30mA, the RCBO will automatically trip, moving the toggle switch to the 'OFF' or intermediate position.
• Função de teste: Press the 'T' (Test) button periodically (e.g., monthly) to verify the residual current tripping mechanism. The RCBO should trip immediately. If it does not trip, the device may be faulty and requires replacement.

6. Manutenção

The Hager ADC810H RCBO requires minimal maintenance, but regular checks are essential for continued safety and performance:

• Inspeção visual: Inspecione periodicamente o dispositivo para verificar se há sinais de danos físicos, descoloração ou conexões soltas.
• Test Button Operation: Perform the test button operation monthly as described in the 'Operation' section.
• Limpeza: If necessary, clean the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Inspeção profissional: It is recommended to have the entire electrical installation, including protective devices, inspected by a qualified electrician at regular intervals as per local regulations.

7. Solução De Problemas

If the RCBO trips unexpectedly or fails to operate correctly, consider the following:

• RCBO Trips Immediately After Reset:
  • Possível causa: Persistent earth fault or short-circuit in the protected circuit.
  • Solução: Disconnect all loads from the circuit. If the RCBO still trips, there is a fault in the fixed wiring. If it holds, reconnect loads one by one to identify the faulty appliance. Consult a qualified electrician.
• RCBO Trips Intermittently:
  • Possível causa: Intermittent earth fault, overloaded circuit, or faulty appliance.
  • Solução: Reduce the load on the circuit. Check appliances for intermittent faults.
• RCBO Does Not Trip When Test Button is Pressed:
  • Possível causa: Faulty RCBO.
  • Solução: The device is not providing residual current protection and must be replaced immediately by a qualified electrician.
• No Power to Circuit, RCBO is ON:
  • Possível causa: Loose connection, fault upstream (e.g., main breaker tripped), or internal device failure.
  • Solução: Check all connections. Verify power supply to the RCBO. If issues persist, consult a qualified electrician.
