Circuit protector for industrial power circuits

This RT16-00C NH00C ceramic square tube fuse provides 80 A gG protection at 500/690 V for industrial power circuits. It carries a 100/50 kA breaking capacity to handle high fault currents safely. The knife shaped contact ensures reliable insertion into compatible NH00C fuse bases. It suits engineers specifying overcurrent protection for three-phase distribution equipment.

Fits NH00C fuse bases in switchgear assemblies

The fuse mounts directly into standard NH00C fuse holders used in low-voltage switchgear and motor control centres. Its ceramic body withstands thermal stress during fault interruption without shattering. The 80 A rating frees designers from derating calculations when protecting conductors sized for that current. No additional mounting hardware is required beyond the matching fuse base.

Knife contact speeds replacement in live panels

The knife shaped contact allows tool-free removal and insertion, reducing downtime during planned maintenance or fault clearance. Ceramic construction eliminates the risk of glass fragmentation under high-energy faults. The 100/50 kA rating covers both prospective short-circuit and rated breaking requirements in a single device. No separate indicator or striker accessory is included with this model.

Questions about this item

How much continuous current can the 80 A gG element carry before it opens?

The fuse is rated for 80 A; sustained current above that value will cause the element to melt and interrupt the circuit.

What temperature rise or heat output should be expected when the fuse runs at 80 A all day?

At rated current the ceramic body and knife contacts dissipate heat normally for a gG fuse; no abnormal temperature rise occurs when installed in a correctly sized NH00C holder.

Which fuse holder or base is required to mount this NH00C knife-contact fuse?

It fits any standard NH00C (size 00C) fuse base that accepts knife-shaped contacts at 500/690 V.
