RS32 100A aR fuse for circuit protection

The OEM Industries RS32 100A aR is a ceramic square tube fast blow fuse designed for line protection in electrical systems. It carries a 100 amp rating and a dual voltage rating of 690V/660V for industrial and generator applications.

Ceramic square tube body for fast blow response

The ceramic construction provides high breaking capacity and thermal stability during fault conditions. Its square tube form factor fits compatible fuse holders or blocks used in panel boards and generator wiring. The fast blow characteristic interrupts overcurrent quickly to protect downstream components.

Replaces worn or blown 100A aR fuses in RS32 series

This fuse serves as a direct replacement for RS32 100A aR links that have operated or aged in service. The upgrade is worth it when restoring full protection coordination in a circuit rated for 690V/660V. It is not suited for circuits requiring time-delay or gG characteristics.

Questions about this item

What voltage does the 690V/660V rating cap for the RS32 fuse?

The RS32 fuse is rated for 690 V AC and 660 V DC, limiting the maximum circuit voltage it can safely interrupt.

What physical format does the ceramic square tube body require for mounting?

The square ceramic tube is designed for bolted or clip-in mounting in compatible fuse blocks or holder assemblies.

How is the fast-blow RS32 fuse installed and what step is often missed?

Insert the fuse into the rated holder, torque the terminal bolts to the holder specification, and verify the aR marking matches the circuit protection plan.
