RS6-00 NGT00 HLS00 690V 100A aR fuse

This RS6-00 NGT00 HLS00 unit is a spiral-style ceramic square tube fuse rated for 690 volts and 100 amps with an aR characteristic. It serves as a line protection device in electrical supply systems where fast-acting semiconductor protection is required. The ceramic tube construction houses the spiral element for reliable fault interruption. It is intended for industrial and generator applications that demand precise overcurrent coordination.

aR characteristic at 690V 100A

The aR classification means this fuse is designed for partial-range protection of power semiconductors rather than full-range cable protection. It will interrupt high fault currents quickly but may not clear low-level overloads that a general-purpose gG fuse would handle. At 690 volts the device is limited to circuits that do not exceed this rated voltage. Coordination with upstream and downstream devices must respect the aR time-current curve to avoid nuisance trips or loss of selectivity.

Replaces worn spiral ceramic square tube fuses

This fuse directly replaces an existing RS6-00 NGT00 HLS00 spiral ceramic square tube unit that has operated or aged in service. The swap is worth it when the original device has reached its end of life or when a spare is needed to minimise downtime in generator and electrical supply panels. It is not for circuits that require a gG or gR characteristic, nor for voltages above 690 volts.

Questions about this item

Should I choose the 100 A version for my 690 V system?

The 100 A rating matches the 690 V aR specification shown for this spiral-style ceramic square tube protector.

What does the 690 V rating mean once the device is installed?

It indicates the maximum AC voltage the protector can safely interrupt in a line protection circuit.

Does the aR classification limit the types of faults this ceramic tube can handle?

The aR rating defines its role as a line protection device for semiconductor circuits under the stated voltage and current.
