Circuit Protection for 500 V Systems
This fuse provides line protection in circuits rated up to 500 V. It carries a 20 A gG rating with a 100 kA breaking capacity. The cylindrical ceramic tube measures 8 by 32 mm. It is suited for industrial and generator applications requiring reliable overcurrent interruption.
Sustained Load Behaviour
The gG characteristic ensures the element withstands normal inrush currents without nuisance opening. Under continuous 20 A loading the fuse runs at its rated temperature rise. A persistent overload above this level melts the element in a predictable time. The 100 kA rating guarantees safe interruption even during severe short-circuit events.
Practical Limits of the gG Standard
The gG curve prioritises cable protection over semiconductor survival. It is not designed for the faster clearing times required by sensitive electronic devices. Coordination with downstream devices must respect the published time-current zones. The 8 by 32 mm form factor fits only holders and bases made for this specific footprint.

Questions about this item
How much heat does the 20 A gG ceramic fuse generate during continuous operation?
The 20 A gG fuse is designed for line protection at 500 V and 100 kA breaking capacity; normal operation produces minimal heat when installed in a correctly rated holder.
What fuse holder or carrier is required for the Ø8×32 mm cylindrical body?
The 8 mm diameter by 32 mm length ceramic tube fits standard RT19-16 or compatible gF1 fuse bases used in industrial panels.
Can the 500 V 100 kA fuse coordinate with older RT19-16 gF1 links already in the distribution board?
Yes, the RO14 shares the RT19-16 gF1 form factor and 500 V 100 kA rating, allowing direct replacement alongside existing links.
