2. Informazioni sulla sicurezza
Always adhere to local and national electrical codes and regulations when installing, operating, or maintaining this device. Failure to do so may result in serious injury, death, or equipment damage.
- L'installazione e la manutenzione devono essere eseguite solo da personale qualificato e autorizzato.
- Ensure all power is disconnected and locked out before beginning any work on the circuit breaker or associated electrical system.
- Use appropriate personal protective equipment (PPE), including insulated gloves, safety glasses, and arc-flash protective clothing.
- Verifica volumetage i valori nominali di corrente dell'interruttore automatico corrispondono ai requisiti dell'applicazione.
- Do not operate the circuit breaker if it appears damaged or has been subjected to abnormal conditions.
3. Configurazione e installazione
The Schneider Electric Compact NSX circuit breaker is designed for panel mounting. Follow these general steps for installation:
- Preparazione: Ensure the mounting surface is clean, dry, and free from obstructions. Verify adequate space for ventilation and access.
- Montaggio: Securely mount the circuit breaker to the designated panel or enclosure using appropriate fasteners. Ensure it is firmly seated to prevent vibration or movement.
- Cablaggio: Connect the incoming and outgoing power cables to the designated terminals. The connector type is Screw. Ensure all connections are tight and secure to prevent loose contacts and overheating. Refer to the product label for correct terminal identification (e.g., 1, 3, 5 for incoming; 2, 4, 6 for outgoing).
- Messa a terra: Connect the circuit breaker to a proper earth ground as per electrical codes.
- Verifica: After installation, visually inspect all connections and ensure no tools or debris are left inside the enclosure.

4. Funzionamento
The Compact NSX circuit breaker features a simple ON/OFF toggle mechanism.
- Accendere: Per chiudere il circuito e consentire il flusso di corrente, spingere con decisione la leva di commutazione in posizione "ON".
- Spegnendo: Per aprire il circuito e interrompere il flusso di corrente, spingere con decisione la leva di comando in posizione "OFF".
- Indicazione di viaggio: In the event of an overload or short circuit, the circuit breaker will automatically trip. The handle will move to an intermediate position, typically between "ON" and "OFF", or to a specific "TRIP" indicator. To reset a tripped breaker, first move the handle fully to the "OFF" position, then push it to the "ON" position. Investigate the cause of the trip before re-energizing the circuit.

This image focuses on the main toggle switch of the circuit breaker, clearly showing the "OFF" indicator. The red button, which typically indicates a tripped state or a test function, is also visible near the switch mechanism.
5. Manutenzione
Regular maintenance ensures the longevity and reliable operation of your Compact NSX circuit breaker. Always disconnect power before performing any maintenance.
- Ispezione visiva: Ispezionare periodicamente l'interruttore automatico per verificare la presenza di eventuali segni di danni fisici, scolorimento, collegamenti allentati o eccessivo accumulo di polvere.
- Pulizia: Use a dry, lint-free cloth to gently clean the exterior of the circuit breaker. Do not use solvents or abrasive cleaners.
- Verifica della connessione: Annually, or as required by local codes, verify the tightness of all electrical connections. Loose connections can lead to overheating and potential failure.
- Test funzionale: If equipped with a test button, periodically test the trip mechanism according to manufacturer guidelines.
6. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| L'interruttore automatico scatta frequentemente. | Overload, short circuit, or ground fault in the circuit. | Identify and correct the cause of the overload or fault. Reduce load, inspect wiring for shorts, or check for ground faults. Do not repeatedly reset a tripping breaker without investigation. |
| L'interruttore automatico non si ripristina. | Persistent fault in the circuit; internal damage to the breaker. | Ensure the fault is cleared. If it still does not reset, the breaker may be damaged and require replacement by a qualified electrician. |
| L'interruttore risulta caldo al tatto. | Overload, loose connections, or internal damage. | Immediately disconnect power. Check for overloads and tighten all connections. If the issue persists, replace the breaker. |
