RS6-00 NGT00 HLS00 line protection

The RS6-00 NGT00 HLS00 is a new circuit protector rated at 250 A and 690 V. It uses a spiral-style ceramic square tube construction for line protection duties. This component is intended for electrical systems that require reliable over-current interruption at these ratings.

Suited for 250 A 690 V circuits

Installers specifying a 250 A aR device at 690 V will find this part matches the requirement. It is not for circuits that demand a different current rating, a different voltage class, or a non-ceramic tube design. Buyers needing alternative ampere values or voltage levels should look at other series.

250 A rating at 690 V

The decisive specification is the 250 A rating at 690 V in an aR spiral-style ceramic square tube. Confirm that both the current and voltage figures match the application before ordering.

Questions about this item

How much heat does the 250 A aR fuse generate during continuous operation?

The fuse is rated for 250 A at 690 V; power dissipation under full load follows the manufacturer's published I²t curves for this aR class.

What fuse holder or mounting hardware is required to install the RS6-00 NGT00 HLS00?

The spiral-style ceramic square tube body fits standard NH00 fuse bases or compatible clip-in holders designed for 690 V aR links.

Will the 690 V aR rating coordinate with older gG-type main breakers in the same panel?

The aR characteristic provides faster short-circuit clearing than gG devices, so selectivity must be verified using the let-through energy charts for each device.
