OEM Industries RS32 200A aR 690V/660V ceramic square tube fast blow fuse

SKU CH-RH7Y-FSGBT

200 A aR ceramic square-tube fast-blow fuse rated for 690 V AC and 660 V DC

  • Amperage200
  • Product typeCircuit Protectors
  • Rated for 200 A to handle high-current circuits
  • Dual voltage rating 690 V / 660 V for versatile installations
  • Ceramic square-tube body provides robust insulation
  • Fast-blow characteristic limits fault energy quickly
  • aR classification suits semiconductor protection needs

Application

The OEM Industries RS32 200A aR is a ceramic square tube fast blow fuse rated for 200 amps and 690V/660V. It serves industrial and automotive electrical systems requiring rapid overcurrent interruption. The aR classification indicates semiconductor protection suited for sensitive equipment.

Compatibility

Verify that your circuit operates within the 690V/660V rating and requires a 200 amp fast blow response. Confirm the physical dimensions match the square tube holder in your panel or generator assembly. Ensure the aR characteristic aligns with the semiconductor devices you are protecting.

Replacement

This fuse replaces an identical RS32 200A aR unit that has opened during a fault event. The upgrade is justified when the original fuse shows signs of aging or when system coordination studies confirm the fast blow curve is necessary. Buyers needing a different ampere rating or voltage class should select another model.

Questions about this item

What comes in the box with the RS32 200A aR fuse and what must be purchased separately?

The package contains the RS32 200A aR ceramic square tube fast blow fuse. Fuse holders or mounting hardware are not included and must be bought separately.

How do I choose between the 690 V and 660 V ratings on the RS32 200A aR fuse?

The fuse carries a dual voltage rating of 690 V and 660 V. Select the rating that matches or exceeds the maximum system voltage of your circuit.

What does the 200 A rating mean when the RS32 fuse is installed in a live circuit?

The 200 A rating indicates the continuous current the fuse can carry. It will open quickly on overcurrent to protect downstream components.
