KETO Battery Disconnector with 100A Fuses
Jean Muller KETO battery disconnector assemblies — The body and both fuse-links on one part number, so nothing arrives half-finished.
Between a battery and the inverter it feeds there has to be something that will both break the circuit on demand and clear a fault. On a 48 V lithium bank running hundreds of amps of DC, that is not a job for an AC device: DC does not cross zero, so the arc has to be driven out rather than waited out.

About the Jean Muller KETO battery disconnector assemblies
The KETO is a fuse-switch-disconnector, which is two things in one body. Pull the handle and the circuit is isolated for maintenance, visibly and lockably. Leave it closed and the NH fuse-links inside it are the overcurrent protection between the battery and the inverter.
Jean Müller build them to DIN EN 60947-3 and type-test them with gG NH links, which is what allows a published short-circuit rating rather than an assumed one.
This listing is the assembly rather than the bare body: the KETO switch and two NH links at the rating in the title, on one part number. It removes the commonest ordering mistake on this product, which is a body arriving with nothing in it.
What is in this package and what it needs
This is a KETO body with two matched NH fuse-links already selected.
Each assembly is one KETO body plus two NH links at the rating in the title. The Package Contents block on this page is the definitive list.

What the job needs
The details that decide whether this suits the system:
- Two links are supplied, at the rating in the title. The Package Contents block is the definitive list.
- Size the fuse from the maximum battery current with a safety factor applied. If the rating here is not the one the design needs, order the bare body and the links you want.
- KETO-00 assemblies: 106 mm wide, 195 mm system size, M8 lugs, 25 – 95 mm².
- KETO-1 assemblies: 184 mm wide, 300 mm system size, M10 lugs, 25 – 150 mm², and the body is rated 250 A.
- KETO switches are moving from blue to black. During the transition either colour may be delivered.
Where this earns its place

Questions we get asked about this inverter
How many fuses are in it?
Two, at the rating in the title. The Package Contents block lists exactly what ships.
What if I need a different fuse rating?
Order the bare KETO body and the two NH links you want. All the ratings we stock are listed separately.
How do I size the fuse?
From the maximum battery current with a safety factor applied, and within what the body accepts.
What is the difference between KETO-00 and KETO-1?
Size and current. KETO-00 is 106 mm wide with M8 terminals and handles up to 160 A; KETO-1 is 184 mm wide with M10 terminals and is rated 250 A.
