OEM Industries RGS4AD 250GH Spiral-Style Ceramic
The OEM Industries RGS4AD 250GH is a spiral-style ceramic fast-blow fuse rated at 140A aR 250V. It provides high-speed circuit protection for industrial and generator electrical supplies. The ceramic body and spiral element ensure rapid interruption under fault conditions. This component suits maintenance engineers and electricians specifying replacement line protection.
Suits 140A 250V aR replacement.
This fuse suits installations that require exactly a 140A aR 250V spiral-style ceramic element in the RGS4AD 250GH series. It is not for circuits needing a different ampere rating, voltage class or time-current characteristic. Buyers who need a slower-acting curve or a different body style should select an alternative part.
140A aR 250V rating confirms correct application
The single specification that decides fitment is the 140A aR 250V rating marked on the fuse. Match this value exactly to the equipment schedule or the original device markings before ordering. Using a fuse with any other rating compromises protection coordination and safety compliance.

Questions about this item
Which amperage rating should I select for my circuit?
This fuse is rated at 140 A; choose it only when the protected circuit is designed for that exact current.
What does the 250 V marking mean once the fuse is installed?
It indicates the maximum voltage the fuse can safely interrupt; do not use it in circuits exceeding 250 V.
How does the aR classification affect performance in my equipment?
The aR rating means the fuse is designed for fast semiconductor protection, clearing short-circuit current very quickly to limit let-through energy.
