2. Informació de seguretat
ADVERTIMENT: Electrical shock hazard. Improper installation or maintenance can result in serious injury or death. All electrical work should be performed by a qualified electrician in accordance with all national and local electrical codes.
- Desconnecteu sempre l'alimentació principal al quadre de servei abans de treballar en qualsevol circuit elèctric.
- Comproveu que l'alimentació estigui apagada amb un voltagel tester abans de tocar cap cable o component.
- Ensure the circuit breaker's amperage rating matches the circuit's requirements.
- No utilitzeu interruptors automàtics danyats o modificats.
- Utilitzeu l'equip de protecció individual (EPI) adequat, incloent-hi guants aïllants i ulleres de seguretat.
- Ensure proper grounding and wiring connections.
3. Instal·lació
Installation of circuit breakers should only be performed by a qualified electrician. The following steps are for informational purposes and highlight the general process.
- Prepare the Load Center: Ensure the main power to the electrical panel is completely shut off. Open the panel cover.
- Identifica la ranura: Locate an available slot on the bus bar within the load center.
- Connectar el cable: Connect the circuit wire (typically black or red) to the terminal screw on the circuit breaker. Ensure the wire is stripped to the correct length and securely tightened. Refer to the breaker's label for wire gauge compatibility and torque specifications.
- Attach Breaker: Hook the rear clip of the breaker onto the retaining clip in the load center.
- Engage Bus Bar: Firmly press the front of the breaker down until it snaps securely onto the bus bar. Ensure it is fully seated.
- Tanca el panell: Once all connections are secure and verified, replace the panel cover.
- Restaura l'alimentació: Torneu a encendre l'alimentació principal.

4. Funcionament
The BR120 circuit breaker operates with a simple toggle switch:
- ON (I): Pushing the toggle switch to the 'ON' or 'I' position closes the circuit, allowing electricity to flow.
- APAGAT (O): Pushing the toggle switch to the 'OFF' or 'O' position opens the circuit, stopping the flow of electricity.
- TRIPPED: If an overload or short circuit occurs, the breaker will automatically move to a tripped position, typically midway between 'ON' and 'OFF', or fully 'OFF' depending on the specific breaker design. This indicates that the circuit has been interrupted for safety.
Per reiniciar un interruptor automàtic que s'ha disparat:
- First, identify and correct the cause of the trip (e.g., unplug overloaded appliances).
- Move the breaker toggle firmly to the full 'OFF' position.
- Then, move the toggle firmly to the full 'ON' position.
5. Manteniment
Circuit breakers generally require minimal maintenance. However, periodic visual inspection is recommended:
- Inspecció visual: Annually, with the main power off, inspect the circuit breakers for any signs of physical damage, discoloration, or loose connections.
- Neteja: Ensure the area around the breakers inside the panel is free from dust and debris.
- Estancament: Periodically check that terminal screws are tight. Do not overtighten.
If any issues are observed, consult a qualified electrician.
6. Solució De Problemes
Aquesta secció tracta els problemes habituals que podeu trobar amb el vostre interruptor automàtic.
| Problema | Causa possible | Solució |
|---|---|---|
| El trencador es desplaça amb freqüència | Overloaded circuit, short circuit, or faulty appliance. | Unplug some devices from the circuit. Inspect appliances for faults. If problem persists, consult an electrician. |
