2. Información de seguridad
ADVERTENCIA: Peligro de descarga eléctrica. La instalación y el mantenimiento solo deben ser realizados por personal cualificado.
- Desconecte siempre la alimentación principal antes de instalar o realizar mantenimiento al disyuntor.
- Ensure the circuit breaker rating (current and voltage) matches the requirements of the circuit it is protecting.
- No utilice el disyuntor si parece estar dañado.
- Siga todos los códigos y regulaciones eléctricas locales y nacionales.
- Asegúrese de que haya una conexión a tierra adecuada cuando sea necesario.
- The C Curve characteristic indicates that the breaker will trip between 5 and 10 times its rated current for short-circuit protection, suitable for general-purpose circuits with moderate inrush currents.

5. Configuración e instalación
Proper installation is critical for the safe and reliable operation of the circuit breaker. Ensure all power is OFF before proceeding.
5.1 Herramientas necesarias
- Destornillador (tamaño apropiado para los tornillos de los terminales)
- Pelacables
- Multímetro (para verificación)
- Personal protective equipment (PPE) such as insulated gloves and safety glasses.
5.2 pasos de instalación
- Desconexión de energía: Locate the main electrical panel and turn off the main power supply to the circuit where the breaker will be installed. Verify with a multimeter that the power is off.
- Montaje en riel DIN:
- Coloque el disyuntor en el riel DIN.
- Engage the top clip of the breaker onto the top edge of the DIN rail.
- Press the bottom of the breaker firmly until it clicks into place on the DIN rail. Refer to Image 5.1 for visual guidance on the mounting mechanism.
- Conexiones de cableado:
- Strip approximately 10-12mm of insulation from the circuit wires.
- Connect the incoming live wire to the top terminal of the circuit breaker.
- Connect the outgoing live wire (to the load) to the bottom terminal of the circuit breaker.
- Ensure all terminal screws are tightened securely to prevent loose connections, which can cause overheating.
- Verificación: Verifique que todas las conexiones estén bien apretadas y tengan la polaridad correcta. Asegúrese de que no haya cables pelados expuestos.
- Restaurar energía: Once installation is complete and verified, restore power at the main supply.

6. Instrucciones de funcionamiento
The GYM8 SP Circuit Breaker is designed for simple operation.
6.1 Encendido del disyuntor
- Ensure the circuit is safe to energize.
- Push the red lever upwards to the "ON" position. The indicator window should show green.
6.2 Apagado del disyuntor
- To de-energize the circuit, push the red lever downwards to the "OFF" position. The indicator window should show red.
6.3 Automatic Tripping
In the event of an overload or short circuit, the circuit breaker will automatically trip to the "OFF" position, protecting the circuit. The lever will typically rest in a middle or fully down position, indicating a trip. Before resetting, identify and rectify the cause of the trip.
7. Mantenimiento
The GYM8 SP Circuit Breaker requires minimal maintenance. Regular inspections are recommended to ensure continued safe operation.
- Inspección visual: Revise periódicamente el disyuntor para detectar cualquier signo de daño físico, decoloración o conexiones sueltas.
- Limpieza: If necessary, gently clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use liquids or abrasive cleaners.
- Pruebas: It is recommended to periodically test the circuit breaker's tripping mechanism by using a dedicated circuit breaker tester, performed by a qualified electrician. Do not repeatedly trip the breaker manually as a test.
8. Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| El disyuntor se dispara con frecuencia. | Overload on the circuit, short circuit, faulty appliance, or incorrect breaker rating. | Reduce load on the circuit, inspect appliances for faults, check wiring for short circuits, or verify breaker rating is appropriate for the load. Consult a qualified electrician. |
| El disyuntor no se reinicia. | Persistent fault (overload or short circuit) still present, or internal damage to the breaker. | Ensure the fault has been cleared. If the breaker still does not reset, it may be damaged and require replacement. Do not force the lever. |
| El disyuntor se siente caliente al tacto. | Loose connections, excessive current draw, or internal fault. | Immediately disconnect power. Check all wiring connections for tightness. Reduce load. If the issue persists, replace the breaker. Consult a qualified electrician. |
