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
- Designed specifically to bridge the physical gap between different fuse sizes, this J636 reducer allows you to securely install 30A Class J fuses into standard 60A Class J fuse clips. This precision-engineered adapter eliminates the need for expensive and labor-intensive panel or disconnect switch replacements when down-sizing your circuit protection requirements.
- Manufactured with high-conductivity copper and a robust mechanical design, this reducer ensures a low-resistance interface between the fuse and the holder. By maintaining high-pressure contact, it prevents localized overheating and arcing—common points of failure in industrial environments—ensuring your motor control center or power distribution board remains thermally stable under continuous load
- This reducer is purpose-built to preserve the integrity of your Class J electrical system, ensuring that the current-limiting properties and high interrupting ratings (up to 200kA) of the 30A fuse remain fully functional. It provides a code-compliant solution for industrial engineers and commercial electricians who need to down-fuse circuits to protect sensitive electronic controllers or smaller motors without compromising arc flash safety.
- Whether you are performing a permanent load reduction on a machine or need a temporary solution for a prototype test, the J636 provides a quick, snap-on installation that requires no special tools. This flexibility makes it an essential component for facility maintenance teams and industrial contractors looking to optimize circuit protection levels while reducing on-site inventory costs.
