FAQ

The 'gG' designation indicates a general-purpose fuse link for full-range breaking capacity. It is designed to protect cables and lines against both overload and short-circuit currents, making it widely applicable in industrial settings. This contrasts with 'aM' fuses, which are designed specifically for motor protection (short-circuit only).

Standard NH fuses of this type typically have a very high breaking capacity to safely interrupt large fault currents. For a 500V AC rating, the breaking capacity is usually 120 kA, which ensures safety even in systems with high prospective short-circuit currents.

Yes, it is generally safe to use a fuse with a higher voltage rating than the system voltage, provided the physical size (NH00) and amperage (100A) are correct for the application. However, you must never replace a fuse with one that has a lower voltage rating, as it may not be able to safely extinguish the arc during a fault.
