Good to know

The gG operating class offers full-range breaking capacity, meaning it can interrupt all overcurrents from the minimum melting current up to the rated breaking capacity. Always verify the fuse base and holder are rated for the same voltage and current. For continuous operation, consider ambient temperature and grouping factors as per local wiring regulations.
