Input fuses

Fuse types:

  • Line protection types in operation classes gL, gG:
    • Nominal fusing voltage ≥ nominal line voltage
    • Nominal fusing current must be designed for at least 10% or 125% of the nominal inverter current depending on the inverter utilization.
  • Power circuit breaker with characteristics B, C:
    • Nominal circuit breaker voltage ≥ nominal line voltage
    • Rated power circuit breaker currents must be 10% above the rated inverter current.
