Will 34244367REVA Work With Magnum Energy Inverter?  

Updated 09/25/2026 | Published 09/24/2026

Question:

I have a Magnum Energy inverter and I need a new 350 amp T fuse and I was wondering if you’re Go Power T fuse would work for this? Thanks

Hey there!

The Go Power Class T Fuse # 34244367REVA is the same style of fuse used with many Magnum Energy inverter setups, but this particular fuse is rated for 400 amps, not 350 amps.

Since your Magnum inverter calls for a 350-amp Class T fuse, I would stick with that specified amperage rather than increasing it to 400 amps. The fuse is there to protect the wiring and inverter, so going larger could reduce that protection.

If you can send me the model number of your Magnum Energy inverter, I can help you find the correct 350-amp replacement.

@KevinD Thanks for the model number! If you have the Magnum Energy MS2012, the Go Power Class T Fuse # 34244367REVA would not be the right replacement since it is rated for 400 amps. Magnum lists a maximum 300-amp time-delay fuse for the MS2012 with the recommended battery cable setup, so I would stick with the fuse size Magnum specifies rather than moving up to a 350- or 400-amp fuse. We do carry the correct 300-amp Class T replacement fuse, which is the Go Power Fuse # 34244366REVA.
