Circuit protection for 160 A lines

The NT1 RT16-1 RO32 is a ceramic square-tube fuse rated at 160 A and 500 V with a 100 kA breaking capacity. It uses a knife-shaped contact for secure mounting in compatible holders. The gG characteristic suits general-purpose overcurrent protection in industrial and generator supply circuits.

Thermal behaviour and power dissipation

The ceramic body and square-tube construction dissipate heat during normal 160 A operation without forced cooling. The gG element melts predictably under sustained overloads while tolerating brief inrush currents. No active cooling or ventilation is required beyond the free air space around the fuse holder.

Knife contact and holder compatibility

The knife-shaped contact mates directly with bolted or clip-type fuse bases designed for the RO32 form factor. No additional hardware, software or indicators are supplied. Installation consists of inserting the fuse into a correctly rated holder and tightening the terminal connections.

Questions about this item

How do I fit the knife-shaped contact into the fuse holder without bending the ceramic tube?

Align the knife blades squarely with the holder clips, press straight in until both sides click, and avoid twisting the ceramic body.

When should the 160 A gG fuse be replaced after a fault?

Replace it immediately after any over-current event; the 100 kA breaking capacity is a single-use rating.

At what continuous current does the 500 V fuse reach its thermal limit?

The 160 A rating is the maximum continuous load; sustained operation above this value will cause the element to melt.
