Description
Mersen fuse reducers allow the use of lower rated fuses in existing equipment having clips with higher ampere ratings. The use of closer rated time-delay fuses can improve circuit protection. For example, renewable or one-time fuses feeding a motor can be replaced with fuses sized closer to the motor nameplate current. Non-rejection reducers will allow Class H, K or R fuses to fit Class H or K clips. Rejection-type reducers will allow only Class R fuses to fit Class R clips or only Class J fuses to fit Class J clips. Class J fuse reducers are not for bolt on applications.
Features
- Engineered to seamlessly adapt existing 100-amp, 600V clips to safely accept smaller 60-amp fuses, this reducer eliminates the need for expensive, time-consuming hardware swap-outs. By stepping down the fuse capacity within your existing enclosure, facility electricians can instantly improve dedicated circuit protection for newly installed, lower-draw motors or upgraded industrial machinery.
- Featuring a specialized mechanical rejection profile, this adapter strictly accepts Class R current-limiting fuses while actively blocking the insertion of lower-tier, non-rejection fuses like Class H or K. This built-in fail-safe guarantees your electrical panel retains its high-performance overcurrent protection, safeguarding valuable downstream equipment from catastrophic faults while maintaining strict compliance with NEC and CEC electrical codes.
- Built to operate flawlessly alongside high-interrupting Class R fuses, this robust fuse reducer easily maintains a massive 200,000 Amp SCCR across heavy-duty 600VAC and 600VDC commercial circuits. It safely channels dangerous short circuits without mechanically deteriorating, giving maintenance crews complete confidence when retrofitting critical high-voltage switchgear.
- Fully UL Listed and CSA Certified, these professional-grade fuse adapters ensure your modified electrical distribution panels easily pass rigorous local safety inspections. Trusting OEM-tested, code-compliant Mersen accessories protects your facility from operational liability and guarantees highly reliable power delivery without the massive downtime required to completely rewire a motor control center.
