Class T fuse holder
The base the fuse needs, and where the battery cable actually lands
160V DC · two ranges, 110-200A and 225-400A · surface mount
A Class T fuse has two bolt holes and nothing else: on its own it connects to nothing. This holder is the part that carries it and that the power cable is bolted to. It mounts on a flat surface, keeps the fuse accessible for inspection, and is rated 160V DC.
Check the stud size before you order. The 110-200A holder has M6 cable studs. That is fine up to about 35mm², but it is not suitable for 50 and 70mm² lugs: for those cross-sections use the 225-400A holder, or the Victron Lynx Class-T Power In with its M10 busbar. The fuse is not included in either case.
Technical data
| DC voltage rating | 160V, both sizes |
| 110-200A holder | fuse studs 8mm, cable studs M6, surface mount |
| 225-400A holder | fuse studs 8mm, cable studs M8 (the maker also lists 3/8" on some versions), 178×51×59mm |
| Fuse included | no |
| Mounting | surface, on a flat panel |
Which one for your cable
Work backwards from the lug, not from the current. With 50 or 70mm² battery cable the only sensible choice in this pair is the 225-400A holder. The smaller one is for secondary circuits and lighter cable. If you are building around a Lynx busbar anyway, the Victron Lynx Class-T Power In takes lugs up to 120mm² and carries two fuses, which usually works out neater than two separate holders.
How it mounts
- Fix the holder to a flat surface, leaving room to get a spanner on both studs.
- Land the power cable on the cable stud with a ring lug, torqued to the maker's figure.
- Fit the fuse across the two fuse studs with the system isolated.
- Keep the cover on in service: the studs are live and uninsulated.
MEGA, Class T or NH: which fuse to choose
Three fuse families are actually used on the DC side of a 48V battery system, and they are interchangeable neither mechanically nor in performance.

| Connection | direct M8 bolt, 50.8mm hole centres | 3/8" studs (225-400A) or M8 (110-200A) | knife contacts: the cable lands on the base, never on the fuse |
| Where it mounts | already built into the Victron Lynx Distributor, with a status LED per position | Victron Lynx Class-T Power In (2 positions, M10 busbar) or a stand-alone holder | NH fuse base PK0/PK1/PK2/PK3, screw-mounted on the panel |
| When to pick it | residential and light commercial systems built around a Lynx busbar: the most compact and the cheapest | large LiFePO4 banks, where a published DC interrupting rating matters. The reference choice in marine and professional off-grid | industrial switchboards, inspectable isolation, cable up to 240mm² |
