Fuse Pack for Industrial Circuits

This pack contains ten cylindrical ceramic-tube fuses rated at 125 amps and 500/690 volts. They are built to the gG class for general-purpose line protection in three-phase systems. The Ø22×58 mm format fits standard industrial fuse holders and disconnectors.

Suited for Maintenance and OEM Stock

Electrical contractors and panel builders who need gG-class replacements for RT14-63, RT18-125 or RT19-100 holders will find the correct rating here. Buyers who need a different current rating, a smaller physical size or a faster-acting characteristic should look at other listings.

125 A gG Rating at 500/690 V

The single specification that decides fit is the 125 A gG rating combined with the 500/690 V AC voltage rating and 100/50 kA breaking capacity. Only select this pack if your equipment calls for exactly those electrical values and the Ø22×58 mm cylindrical form factor.

Questions about this item

What fuse holder size matches the 22 mm diameter of these RO17 fuses?

Use a holder rated for Ø22 mm cylindrical fuses with a 58 mm length to fit the ceramic tube body.

Can the 125 A gG rating protect circuits that also use RT14-63 or RT18-125 devices?

Yes, the gG characteristic coordinates with those reference types for general-purpose line protection at 500/690 V.

How do I confirm a fuse has operated after a fault?

Inspect the ceramic tube for a visible break in the element or use a continuity tester across the end caps.
