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

1. Introdución

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. Instrucións de seguridade

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.
• Ensure proper grounding of the electrical system.
• Verify that the device ratings (voltage, current, breaking capacity) match the requirements of your electrical installation.
• Non poñas en funcionamento o dispositivo se parece estar danado.
• Regularly test the residual current function using the test button.

3. Produto rematadoview

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 imaxe mostra a parte dianteira 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 compoñentes clave inclúen:

• Interruptor de alternancia: For manual ON/OFF operation and indication of trip status.
• Botón de proba: Used to periodically test the residual current tripping mechanism.
• Terminais de conexión: Clearly marked for phase (L) and neutral (N) input and output.
• DIN Rail Mounting Clip: For secure installation on a DIN rail.

4. Instalación

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

1. Desconexión de alimentación: Ensure the main power supply to the installation is completely disconnected and secured against accidental re-connection.
2. Montaxe: 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: Aperte todos os parafusos dos terminais ao par especificado polo fabricante para evitar conexións soltas e sobrequecemento.
6. Verificación: Double-check all connections for correctness and security before restoring power.

5. Funcionamento

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

• Encendido: Empurre o interruptor basculante cara arriba á posición "ON".
• Apagado: Empurre o interruptor basculante cara abaixo á posición "OFF".
• 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.
• Función de proba: 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. Mantemento

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

• Inspección visual: Inspeccione periodicamente o dispositivo para detectar calquera signo de danos físicos, decoloración ou conexións soltas.
• Test Button Operation: Perform the test button operation monthly as described in the 'Operation' section.
• Limpeza: Se é necesario, limpe o exterior do dispositivo cun pano suave e seco. Non empregue produtos de limpeza abrasivos nin disolventes.
• Inspección profesional: 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 Solución de problemas

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

• RCBO Trips Immediately After Reset:
  • Causa posible: Persistent earth fault or short-circuit in the protected circuit.
  • Solución: 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:
  • Causa posible: Intermittent earth fault, overloaded circuit, or faulty appliance.
  • Solución: Reduce the load on the circuit. Check appliances for intermittent faults.
• RCBO Does Not Trip When Test Button is Pressed:
  • Causa posible: Faulty RCBO.
  • Solución: The device is not providing residual current protection and must be replaced immediately by a qualified electrician.
• No Power to Circuit, RCBO is ON:
  • Causa posible: Loose connection, fault upstream (e.g., main breaker tripped), or internal device failure.
  • Solución: Check all connections. Verify power supply to the RCBO. If issues persist, consult a qualified electrician.
