2. Informazioni sulla sicurezza
AVVERTIMENTO: Electrical installations should only be performed by qualified and licensed electricians. Failure to follow these safety instructions can result in electric shock, fire, serious injury, or death.
- Always disconnect power at the main service panel before installing, servicing, or removing the circuit breaker.
- Verificare che il volumetage i valori nominali di corrente dell'interruttore automatico corrispondano ai requisiti del tuo impianto elettrico.
- Do not use the circuit breaker if it appears damaged or has been dropped.
- Assicurarsi che tutti i collegamenti siano ben saldi e sicuri per evitare surriscaldamenti e archi elettrici.
- This device is designed for short-circuit protection. It is not intended for overload protection or as a primary ON/OFF switch for frequent operation.
- Funzionare entro l'intervallo di temperatura specificato da -20°C a 50°C.
3. Configurazione e installazione
The Hager SBN125 circuit breaker is designed for easy installation on a standard DIN-rail within an electrical distribution board.
3.1 Contenuto della confezione
- 1x Hager SBN125 1-Pole Circuit Breaker
3.2 Passaggi di installazione
- Disconnessione dell'alimentazione: Before beginning any work, ensure that the main power supply to the electrical panel is completely disconnected and locked out to prevent accidental re-energization.
- Montaggio: Locate an available space on the DIN-rail within your electrical distribution board. Position the SBN125 circuit breaker onto the DIN-rail, ensuring it clicks securely into place.
- Cablaggio:
- Connect the incoming phase (live) wire to the top terminal of the circuit breaker.
- Connect the outgoing phase (live) wire to the bottom terminal of the circuit breaker, leading to the circuit it protects.
- Ensure all wire connections are stripped to the correct length and inserted fully into the terminals. Tighten the terminal screws firmly to the manufacturer's specified torque (if available) to prevent loose connections.
- Verifica: Controllare attentamente tutti i cavi per verificarne la correttezza e la sicurezza. Assicurarsi che non vi siano fili scoperti.
- Ripristina alimentazione: Once installation is complete and verified, restore power to the main service panel.
4. Istruzioni per l'uso
The Hager SBN125 is a manual switch designed for short-circuit protection. It has two primary operating states:
- ON Position (Up): Pushing the toggle switch upwards connects the circuit, allowing electrical current to flow.
- OFF Position (Down): Pushing the toggle switch downwards disconnects the circuit, interrupting the electrical current.
In the event of a short circuit, the device is designed to interrupt the current flow, protecting the circuit. This is a non-automatic switch, meaning it does not trip automatically like a miniature circuit breaker (MCB) for overload protection. Its primary function is to provide a manual means of isolating a circuit and to offer short-circuit protection.
5. Manutenzione
The Hager SBN125 circuit breaker requires minimal maintenance. Regular inspections are recommended to ensure continued safe operation.
- Ispezione visiva: Ispezionare periodicamente l'interruttore automatico per verificare la presenza di eventuali segni di danni fisici, scolorimento o collegamenti allentati.
- Pulizia: If necessary, gently clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use liquid cleaners or solvents. Ensure power is disconnected before cleaning.
- Controllo professionale: Si consiglia di far ispezionare periodicamente l'impianto elettrico, compresi gli interruttori automatici, da un elettricista qualificato.
6. Risoluzione Dei Problemi
If you experience issues with your Hager SBN125 circuit breaker, consider the following common troubleshooting steps:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Circuit breaker does not switch ON. | No power to the circuit breaker; internal fault. | Check the main power supply. If power is present and the breaker still won't switch, it may be faulty and require replacement by a qualified electrician. |
| Nessuna alimentazione al circuito collegato. | Circuit breaker is OFF; loose wiring; faulty breaker. | Ensure the circuit breaker is in the ON position. Disconnect power and check all wiring connections for tightness. If issues persist, consult a qualified electrician. |
| L'interruttore automatico è caldo. | Loose connections; excessive current (overload/short circuit). | Immediately disconnect power. Check for loose connections. While this device offers short-circuit protection, persistent heat may indicate an underlying issue in the circuit or an overload condition that this non-automatic switch is not designed to trip for. Consult a qualified electrician. |
For problems not listed here or if solutions do not resolve the issue, contact a qualified electrician or Hager customer support.
