It also highlights advanced features like overload, short circuit, lightning, leakage, over-undervoltage protection, smart reset, and real-time monitoring.

4. Installazione

The EARU 32A Circuit Breaker is designed for DIN-rail mounting. Ensure the installation environment is dry, well-ventilated, and free from corrosive substances.

Fasi di installazione:

1. Montaggio: Securely attach the circuit breaker to a standard DIN rail in your electrical panel.
2. Collegamenti elettrici: Fare riferimento a Immagine 1 for the wiring diagram. Connect the incoming Line (L) and Neutral (N) wires to the top terminals and the outgoing load wires to the bottom terminals. Ensure the Protective Earth (PE) is correctly connected.
3. Serraggio dei terminali: Use appropriate tools to tighten all fastening screws on the terminals to ensure secure electrical contact and prevent loose connections, which can cause overheating or arcing.
4. Verifica: Prima di ripristinare l'alimentazione, verificare nuovamente che tutti i collegamenti dei cavi siano corretti e ben serrati.

5. Istruzioni per l'uso

Basic Operation and Leakage Protection Test

Follow these steps for normal operation and to periodically test the leakage protection function of your circuit breaker.

Immagine 4: This image illustrates the basic operating instructions. Fase 1: To power on, pull up the operating handle (red switch) and ensure the 'R' button is protruding, indicating a power-on state. Fase 2: If the handle jumps down automatically and the 'R' button bounces, it signifies a normal power-off state. Fase 3: If the 'R' button is pressed and the handle does not jump down, it indicates a problem. Fase 4: After a successful test or reset, the device returns to a powered-on state.

Immagine 5: Detailed instructions for inspecting the leakage protection device. Fase 1: With the operating handle pulled up and the 'R' button not protruding (power-on state), press the 'Test' key to test the leakage protection device. Fase 2: If the handle jumps down automatically and the 'R' button bounces, the device is in a power-off state, indicating the leakage protection device is functioning normally. Fase 3: If the 'Test' switch is pressed and the handle does not jump down, and the 'R' button does not automatically pop up, the device is in an energized state, indicating a problem with the leakage protection device, and it cannot provide protection. A new leakage device needs to be replaced. Fase 4: After a normal inspection (handle automatically jumps down, 'R' button automatically pops up), the device is in a power-off state. Press the 'R' button that just popped up, and then pull up the operating handle to power on the appliance normally.

Parameter Setting (Adjustable Voltage and Current Protector)

The EARU Circuit Breaker allows for adjustment of various protection parameters. The following video demonstrates how to set these parameters.

6. Manutenzione

Regular maintenance ensures the longevity and reliable operation of your EARU Circuit Breaker.

• Ispezione periodica: Visually inspect the circuit breaker and its connections regularly for any signs of damage, discoloration, or loose wiring.
• Pulizia: Mantenere il dispositivo pulito e privo di polvere e detriti. Utilizzare un panno asciutto e morbido per la pulizia. Non utilizzare detergenti liquidi o solventi.
• Pulsante di prova: Periodically press the 'Test' button to verify the functionality of the leakage protection. Refer to the 'Leakage Protection Device Inspection' section for detailed steps.
