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

The Mersen J216 fuse reducer is engineered to cleanly bridge the physical gap between different current thresholds, allowing a smaller 100A Class J fuse to seat perfectly into standard 200A clips. This eliminates the massive labor and hardware costs of replacing entire high-amp switch blocks or safety disconnect units when circuit requirements downsize.
Rated for high-voltage industrial circuits up to 600VAC, this rejection-type component safely maintains full circuit integrity and system coordination. It is fully compatible with ultra-fast acting or time-delay fuses, safeguarding sensitive downstream assets like motors and branch circuits without introducing vulnerability.
These specialized Class J reducers are intentionally crafted for clip-in installations to maximize versatility, which means they are not designed for direct bolt-on configurations. This targeted design streamlines clip-in integration across a vast range of standard distribution panels, switchgear, and commercial motor control centers.
Fabricated by Mersen Canada Toronto with official UL Listed and CSA Certified distinctions, this component guarantees absolute compliance with local electrical codes and strict facility standards.
