Class R fuses and blocks
Class R fuses
The 250 VAC/ 125 VDC Class R fuses can be used in AC circuits up to 250 VAC or DC circuits up to 125 VDC. The 600 V fuses can be used for AC or DC circuits. They have the high amp interrupting capacity (AIC) required for fusing circuits powered by batteries. They can be used to protect wiring to small inverters (100-700 watts) and wiring from charging sources. These UL Listed fuses can be used in fused safety disconnect switches and most large system sub-array combiners.

Class R Fuse Blocks
Use these fuse blocks with the Class R 250 VAC fuses. Bare wire ends fit into the screw terminals on each end of the fuse block. The small fuse block holds 10-30 A fuses and accepts up to #2 AWG wire. The medium size block holds 40-60 A fuses and also accepts up to #2 AWG wire. The large size block holds a 100 A fuse and accepts up to #1/0 AWG wire. Small and medium size blocks are available in one-pole and two-pole versions. These do NOT fit the 600 V fuses.
