Picking an FDS switch
Start with the fuse class. Class CC fits the 30 A switches. Class J comes in 30 A and 60 A. Then pick the pole count. 1-pole switches carry 347 V AC or 125 V DC. 2 and 3-pole switches carry 600 V AC. Send the load amps and voltage and we will match the switch and the fuse.
See the MSP Class J fused disconnect page, the Marathon collection or the cross reference hub for Bussmann to Marathon fuse crosses.
