Motor control centres, combination starters and transformer feeders need a compact fuse that rides through inrush and still limits fault current. The Littelfuse JTD090 is a 90 A POWR-PRO Class J time-delay, dual-element fuse rated 600 VAC and 300 VDC, with a 200 kA AC interrupting rating. This listing is a package of 5, matching Littelfuse's carton.
Why industrial electricians pick it
- Dual-element time delay reduces nuisance openings on high-inrush motor and transformer loads.
- Class J size is compact compared with RK-class fuses of the same rating.
- Littelfuse rates JTD fuses for Type 2 no-damage protection of NEMA and IEC motor circuit components.
- 200 kA AC interrupting rating (300 kA Littelfuse self-certified) and 20 kA DC.
- UL Listed and CSA Certified.

Pro tip from the counter
If a 90 A Class J fuse opens with no fault found, check the fuse clips before loading a new one. Discoloured or loose clips heat the blade and cause nuisance openings, so have worn clips or the holder replaced first or the replacement fuse will fail the same way.
Best for: motor control centres, fused combination starters, transformer feeders, plant maintenance spares
