4. Configuració i instal·lació
4.1 Instal·lació mecànica
- Desconnexió d'alimentació: Before beginning any work, ensure that the main power supply to the circuit is completely disconnected at the service panel. Verify with a voltage provador.
- Muntatge: The circuit breaker is designed for DIN rail mounting. Snap the device onto the standard 35mm DIN rail within your electrical panel or enclosure.
- Espai lliure: Ensure adequate space around the device for ventilation and access to terminals.
4.2 Electrical Wiring (3-Pole Configuration)
Refer to the wiring diagram on the device and below for correct connections. The 3-pole version is suitable for three-phase systems or specific single-phase applications requiring three conductors.
- Input Terminals (IN): Connect the incoming live (L1, L2, L3) and neutral (N) wires from your power source to the corresponding "IN" terminals at the top of the circuit breaker.
- Output Terminals (OUT): Connect the outgoing live (L1, L2, L3) and neutral (N) wires to the load (e.g., appliances, sub-panel) from the corresponding "OUT" terminals at the bottom.
- Estrènyer les connexions: Use appropriate tools to securely tighten all screw terminals. Loose connections can cause overheating and fire hazards.
