Configuració i instal·lació
Proper installation is crucial for the safe and effective operation of the circuit breaker. Follow these steps carefully:
- Seleccioneu la ubicació de muntatge: Choose a dry, accessible location on a panel, away from excessive heat or vibration. Ensure sufficient space for wiring and access to the reset button.
- Preparació de la superfície de muntatge: Drill appropriate holes for mounting screws and the breaker body, if recess mounting. Refer to the product dimensions for precise measurements (6 x 6 x 6 inches).
- Mount the Breaker: Secure the circuit breaker to the panel using appropriate fasteners through the mounting holes.
- Connexions de cable: Connect the positive (+) input wire from the power source to one terminal and the positive (+) output wire to the protected device (e.g., winch, windlass) to the other terminal. Ensure all connections are tight and secure. This is a 2-pole breaker.
- Verifiqueu el cablejat: Double-check all wiring connections for correctness and polarity before restoring power.
- Restaura l'alimentació: Un cop finalitzada i verificada la instal·lació, restableix l'alimentació del circuit.
Instruccions de funcionament
The Lewmar 68000348 circuit breaker operates automatically to protect your electrical system:
- Funcionament normal: Under normal conditions, current flows through the breaker without interruption.
- Overcurrent Trip: Si el corrent supera els 50 Amps due to an overload or short circuit, the thermal mechanism within the breaker will heat up and automatically trip, interrupting the circuit. The red reset button will typically pop out.
- Resetting the Breaker: To reset the breaker after a trip, first identify and rectify the cause of the overcurrent (e.g., remove the overload, fix the short circuit). Once the issue is resolved, firmly press the red reset button until it clicks back into place. If the breaker immediately trips again, the fault has not been cleared.
Manteniment
The Lewmar 68000348 circuit breaker requires minimal maintenance:
- Inspecció periòdica: Regularly inspect the breaker and its connections for any signs of corrosion, loose wiring, or physical damage.
- Neteja: Keep the breaker clean and free of dirt, dust, and moisture. Use a dry cloth for cleaning.
- Comprovació del terminal: Periodically check the tightness of the electrical terminal connections.
