NH Fuse-link 100A for Keto 1
Jean Muller NH fuse-link — Two per disconnector — match the size to the body and the rating to the battery.
A fuse-link is the part that actually clears a fault. The switch around it isolates; the link interrupts, and on a battery circuit that is what stands between a cable fault and a fire.

About the Jean Muller NH fuse-link
These are gG links to IEC 60269 and DIN VDE 0636-2, rated AC500V with a 120 kA breaking capacity and a combi indicator that shows at a glance whether the link has operated.
Two go in each KETO disconnector, one per pole. Match the size to the body — NH00 links in a KETO-00, NH1 in a KETO-1 — and take the rating from the maximum battery current with a safety factor applied.
The NH00 links carry isolated gripping lugs and the NH1 links live ones, which matters when the link is being changed in a live board.
What does this fit?
This is the overcurrent protection inside a KETO disconnector.
The size has to match the body. NH00 links (article N50…) go in a KETO-00; NH1 links (article N10…) go in a KETO-1. Two links per disconnector, and the rating comes from the maximum battery current with a safety factor applied.

What the job needs
The details that decide whether this suits the system:
- Two links per disconnector.
- NH00 links fit the KETO-00; NH1 links fit the KETO-1. They are not interchangeable.
- gG characteristic, IEC 60269 and DIN VDE 0636-2, AC500V, 120 kA breaking capacity, blade contact, combi indicator.
- NH00 links have isolated gripping lugs; NH1 links have live gripping lugs.
- Size from the maximum battery current with a safety factor applied. Check the disconnector's maximum permissible power loss per link — 23 W on the KETO-1 — against the link's dissipation.
- Approvals are EAC and VDE.
Where this earns its place
The NH fuse-link is specified most often for these jobs.

Questions we get asked about this inverter
How many do I need?
Two per disconnector, one per pole.
Will an NH00 link fit a KETO-1?
No. The sizes are not interchangeable: NH00 links go in a KETO-00 and NH1 links go in a KETO-1.
What does gG mean?
It is the utilisation category: full-range protection of cables against both overload and short circuit, as opposed to aM which only protects against short circuit.
What rating should I choose?
Size it from the maximum battery current with a safety factor applied, within what the body accepts — up to 160 A on a KETO-00 and up to 250 A on a KETO-1.
What is the combi indicator for?
It shows whether the link has operated, so a blown fuse can be found without pulling every link out.
