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 166 fuse reducer provides a precise, physical fit that lets you install a lower-rated 60A fuse directly into 100A fuse clips. This eliminates the massive expense of replacing an entire safety switch or commercial panelboard when down-sizing your electrical circuits.
Engineered specifically for heavy-duty commercial and industrial environments, this non-rejection fuse reducer handles up to 600V AC power configurations seamlessly. It allows maintenance electricians to optimize overcurrent protection across high-voltage motor branches and feeders without compromising the structural integrity of the branch circuit.
Designed for broad physical compatibility, this adapter accommodates standard Class H, Class K, and Class R fuses within traditional Class H or K fuseblocks. This versatile design ensures service technicians can adapt varying historical fuse types to legacy infrastructure without needing custom modifications.
This commercial-grade accessory is fully UL Listed (Guide No. IZZR) and CSA Certified, assuring inspectors that your industrial control panels remain up to standard. The rugged construction maintains an ultra-secure mechanical grip on power distribution clips, avoiding dangerous arc flashes, high-resistance hot spots, or voltage drops.
