Line fuses and miniature circuit breakers
Line fuses and miniature circuit breakers are used for protecting the supply system cables. For fusing, use fuses and miniature circuit breakers with the following properties:
Type class | Requirement |
---|---|
Fuses in utilization categories gL, gG | Fusing voltage ≥ nominal line voltage |
Miniature circuit breaker with characteristics B, C, D | Nominal miniature circuit breaker voltage ≥ nominal line voltage |
Nominal currents of the miniature circuit breaker must be 10% higher than the nominal line current of the inverter |
Adhere to the country-specific and system-specific regulations when carrying out the fusing. If required, observe the notes in the chapter "UL-compliant installation".
