Ø10×38 mm ceramic tube fuse

This pack contains twenty cylindrical ceramic fuses rated at 25 A with a gG characteristic. They suit industrial and commercial circuits that require reliable overcurrent protection. Electricians and maintenance teams use them in fuse holders designed for the 10×38 mm form factor.

500/690 V 50 kA breaking capacity

The ceramic body withstands 500 V AC and 690 V AC while interrupting prospective short-circuit currents up to 50 kA. Under sustained overload the fuse element melts predictably, limiting let-through energy and protecting downstream equipment. The high breaking rating ensures safe operation on supply networks with high fault levels.

Cross-reference compatibility

The RO15 model replaces RT18-32, RT14-20, RT19-25 and gF2 types, allowing direct substitution in existing fuse bases. Installers must verify that the holder accepts the 10×38 mm dimensions and the gG time-current curve. Circuits requiring a different characteristic or voltage rating will need an alternative fuse.

Questions about this item

Does the ceramic body of the RO15 run cooler than glass fuses during continuous 25 A loads?

The ceramic tube construction handles sustained 25 A current at 500/690 V without the thermal stress that can affect glass-bodied fuses.

What fuse holders accept the Ø10 × 38 mm dimensions of these RO15 fuses?

Any holder or carrier rated for 10 mm diameter by 38 mm length cylindrical fuses will accept the RO15 directly.

Will the gG characteristic of the RO15 coordinate with older gF2-rated fuse links in the same circuit?

Both gG and gF2 are full-range breaking classes for general-purpose protection, so the RO15 can replace legacy gF2 links rated at 25 A.
