Mains fuses

Fuse types:

• Line protection types in operation classes gL, gG:
• Nominal fusing voltage ≥ nominal line voltage
• The nominal fusing current must be designed for at least 100% of the inverter nominal input current depending on the inverter utilization.
• Power circuit breaker with characteristics B, C:
• Nominal circuit breaker voltage ≥ nominal line voltage
• The nominal currents of the power circuit breakers must be 10% higher than the nominal inverter current.
