RT16-00 NT00 80 A gG fuse

The RT16-00 NT00 is a ceramic square-tube fuse rated 80 A with a gG characteristic for general-purpose line protection. It operates at 500 V AC and 690 V AC and carries a breaking capacity of 100 kA at 500 V and 50 kA at 690 V. The knife-shaped contact fits compatible fuse bases in industrial and generator installations.

Suitable for 80 A gG circuits at 500/690 V

This fuse suits circuits that require an 80 A gG device with a 100/50 kA breaking capacity at the stated voltages. It is not for applications needing a different current rating, a different breaking capacity, or a non-gG time-current characteristic. Buyers who need a higher or lower ampere value should select another rating.

80 A gG rating at 500/690 V

The single specification that decides fit is the 80 A gG rating combined with the 500 V / 690 V voltage rating and 100/50 kA breaking capacity. Verify that the circuit design calls for exactly these values before installation.

Questions about this item

How much power does the 80 A gG fuse dissipate when it runs continuously?

At its rated 80 A the ceramic square-tube fuse carries load without generating significant heat; normal operation stays cool inside a correctly ventilated fuse holder.

What must the installer already have to fit this knife-contact fuse?

A compatible NH size 00 fuse base or fuse switch-disconnector with knife-contact terminals rated for at least 500 V AC is required.

Will this 500/690 V fuse coordinate with existing 500 V gG links in the same panel?

Yes — both share the 500 V AC rating and gG characteristic, so selectivity between the 80 A link and older 500 V links follows standard time-current curves.
