250V Class R

The 250V Class R is part of the Mersen (formerly Ferraz Shawmut) fuse holders & blocks line, distributed by Gross Automation.

250V Class R

Ferraz Shawmut 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-ejection 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.
