Jean Müller KETO-00 Fuse Switch-Disconnector with 2 Fuses 100A 250V DC for Batteries
This is the KETO-00 ready to go: the Jean Müller fuse switch-disconnector supplied with two 100A NH fuse links already in place, one for the positive pole and one for the negative. It sits between the battery bank and the inverter and does two jobs in one device: it isolates the DC side by hand, for maintenance or an emergency, and it protects it from short circuits through the fuses.
Unlike the bare body there is nothing else to order: the pair of links is already sized at 100A, gG general-purpose class, with a breaking capacity declared by Jean Müller of 120kA. It is the convenient choice when the bank’s charge and discharge current, margin included, falls inside that figure.
The kit works to 250V DC, the figure Jean Müller gives for the KETO 00, so it covers 48V and 51.2V banks, single or paralleled. Terminals are M8 flat for 25mm² to 95mm² cable, width is 106mm with a 195mm system size, and mounting is on DIN rail. Installation is a job for a qualified electrician, to local wiring rules.
