RS6-00 NGT00 HLS00 690V~315A aR Spiral-style

This is a new circuit protector rated at 315 amps and 690 volts. It uses a spiral-style ceramic square tube construction for line protection. The device belongs to the RS6-00 NGT00 HLS00 series. It is intended for electrical supply systems requiring this specific current and voltage rating.

Replaces protectors with lower amp or voltage

Install this unit when the circuit demands 315 amps at 690 volts and the existing protection does not meet those values. The ceramic tube design suits applications specifying this form factor. The upgrade is justified when the system requires the exact series designation and performance class.

Suits engineers specifying RS6-00 NGT00 HLS00 series

Buyers needing a different ampere rating, voltage class or physical package should select another model. This protector does not fit circuits operating outside the stated 315 amp and 690 volt parameters. It is not for use where an alternative series or technology is mandated.

Questions about this item

What size fuse holder does the 315 A ceramic square tube require?

The fuse body is a spiral-style ceramic square tube rated for 690 V and 315 A, so the holder must accept that exact form factor and current rating.

Which orientation must the spiral-style ceramic square tube be mounted in?

Install the tube with the spiral element horizontal and the end caps fully seated in the 690 V rated holder; the common error is leaving a gap at one cap.

How do I know when the 315 aR fuse has operated and needs replacement?

After a fault the ceramic body shows discolouration or a visible break in the spiral element; the fuse cannot be reset and must be replaced with an identical 315 A unit.
