PRODUCT DETAILS
The Go Power! F-series is the Class T, DC-rated replacement fuse for the FBL fuse block supplied in Go Power! inverter install kits — available in 110, 200, 300 and 400 amp ratings for 12, 24, 32 and 48 V battery systems. Class T fuses have the very high interrupt rating a large AGM or lithium battery bank demands: they clear a dead short without arcing or rupturing, which an ANL or MIDI fuse cannot guarantee. Always replace like for like — same class, same amp rating.
Fits more than Go Power! blocks
These are standard Class T (JLLN / A3T form factor) fuses, so they also fit Blue Sea Systems, Littelfuse and other Class T fuse holders. If your existing fuse is Class T and the amperage matches, this is a direct replacement.
Built to the standard RV manufacturers install
Go Power! has designed mobile power since 1996 and is the inverter brand fitted at the factory by Jayco, Forest River, Thor and other leading RV builders. These are the same fuses the plants and dealers use, backed by a North American support team (part of Dometic).
What's in the box
One Class T fuse in the amperage selected. Fuse block sold separately — see the Go Power! Class T Fuse with Block if you need the holder too.

FAQ
Why Class T instead of ANL or MIDI?
Class T fuses interrupt very high DC fault currents (tens of thousands of amps) without arcing. Lithium and large AGM banks can push thousands of amps into a short, which exceeds what ANL and MIDI fuses are rated to clear safely. ABYC and most inverter manufacturers call for Class T on these circuits.
Can I use a higher-rated fuse if this one keeps blowing?
No. The fuse is sized to protect the battery cable. A fuse that blows repeatedly means an overload or a fault that needs to be found and fixed.
Will this fit my Blue Sea Systems fuse block?
Yes. Go Power! F-series fuses are standard Class T fuses and fit Blue Sea 5007 / 5502 series blocks and other Class T holders. Check that the amperage matches the original.
Which fuse does my Go Power! install kit use?
GP-DC-KIT1 and KIT2 (100–1,000 W inverters) use the 110 A; KIT3 (1,100–1,800 W) uses the 200 A; KIT4 (2,000–2,500 W) uses the 300 A; KIT5 (2,500–3,000 W) uses the 400 A. When in doubt, match the fuse already in your block.
Is the fuse block included?
No — this listing is the fuse only. The Go Power! Class T Fuse with Block includes the mounting block, protective cover and fuse.
Is Go Power! the fuse my RV came with?
Very likely. Go Power! has supplied RV manufacturers since 1996 and is fitted at the factory by Jayco, Forest River, Thor and many other brands; this is the same replacement part the dealer would order.
