NT1 RT16-1 RO32 fuse link

The NT1 RT16-1 RO32 is a ceramic square tube fuse link with knife shaped contacts designed for line protection in electrical installations. It operates at 500 V and carries a 100 kA breaking capacity. The gG characteristic provides general purpose overcurrent protection for conductors and equipment. This component is supplied new and ready for installation.

Electrical contractors and panel builders

This fuse link suits engineers specifying 125 A gG protection in 500 V industrial circuits. It is not for installers who need a different rated current or voltage class. It is not for applications requiring a cylindrical body or blade style contact arrangement. It is not for circuits where a lower breaking capacity device is specified.

125 A gG rating at 500 V

The single specification that decides fit is the 125 A gG rating at 500 V with 100 kA breaking capacity. Verify that the protected circuit demands exactly this current rating and voltage level. The knife shaped contacts must match the fuse base or holder used in the panel. No other electrical parameter overrides this selection.

Questions about this item

Does the ceramic square tube fuse with knife shaped contact come alone or with a holder?

The listing shows the NT1 RT16-1 RO32 125A gG fuse itself; a matching fuse holder or base must be purchased separately if one is not already installed.

The title lists NT1 RT16-1 RO32 125A gG — how do I know this rating fits my circuit?

Choose this model when the circuit requires a 125 A gG-class fuse rated for 500 V AC with a 100 kA breaking capacity and a knife contact.

What does the 100 kA breaking capacity mean when the fuse is installed?

It means the fuse can safely interrupt fault currents up to 100 kA at 500 V without rupturing the ceramic body.
