690 V aR Circuit Protector
This 690 V aR spiral-style ceramic square tube provides line protection for industrial and commercial electrical systems. Rated at 200 A, it is built for circuits that demand fast-acting fault interruption. The ceramic body and spiral element suit high-voltage distribution panels and generator feeders. It is intended for qualified electricians and maintenance teams specifying aR-class overcurrent devices.
Not for low-voltage or gG applications
This protector suits installations that require aR characteristic curves at 690 V and 200 A. Buyers who need a general-purpose gG fuse or a device rated below 690 V should look elsewhere. It does not fit holders designed for cylindrical or blade-type fuses. Systems requiring coordinated selectivity with downstream breakers not rated for aR curves may need a different protection strategy.
200 A continuous headroom
The 200 A rating handles sustained loads up to that value while clearing short-circuit faults rapidly. It runs out when fault currents exceed the aR interrupting capacity defined for the series or when the application calls for a higher voltage rating than 690 V. Continuous operation above 200 A or in ambients beyond the ceramic tube’s thermal limits will require a larger frame size.

Questions about this item
What voltage rating must my circuit support for the RS6-00 NGT00 HLS00 690V 200A aR fuse?
The fuse is rated for 690V AC, so your circuit must not exceed this voltage.
Can the RS6-00 NGT00 HLS00 690V 200A aR fuse coordinate with existing 200A breakers?
As an aR class fuse it provides fast short-circuit protection; coordination with 200A breakers depends on their time-current curves.
How do I verify the RS6-00 NGT00 HLS00 690V 200A aR fuse is intact after installation?
Measure continuity across the ceramic tube with a multimeter; a closed circuit indicates the spiral element is intact.
