Fuse for 50 A circuits

The OEM Industries RT16-00C NH00C is a ceramic square tube fuse rated at 50 A for 500/690 V systems. It uses a gG characteristic and knife shaped contact for line protection in electrical installations. The breaking capacity is specified as 100/50 kA.

Suited for industrial panels

This fuse fits circuits that require a 50 A gG device with ceramic body and knife contacts at 500/690 V. It is not for buyers who need a different current rating, a different voltage class, or a blade style contact. It also does not suit applications that call for a semiconductor protection characteristic.

No bundled accessories

The product is supplied as the fuse unit only. No additional hardware, indicators or mounting blocks are included in the package. Installation relies on standard NH00C fuse holders that accept knife shaped contacts.

Questions about this item

Does this fuse need a fuse holder with knife-blade contacts to work?

Yes, the knife-shaped contact requires a compatible NH00C fuse base that accepts blade terminals for a secure electrical connection.

Will this 50 A gG fuse coordinate with an existing 100 A upstream breaker?

The fuse is rated for 100 kA breaking capacity at 500 V and 50 kA at 690 V, so it can safely interrupt faults downstream of a 100 A breaker when selectivity is verified.

How can I confirm the fuse is intact after installation?

Measure continuity across the knife contacts with a multimeter; a low resistance reading shows the ceramic tube element is unbroken.
