MTA covers MIDI fuse protection for 12V and 24V systems: the MIDI fuse itself in 30A-100A rated to 32V maximum, a single MIDI holder, and a three-way holder for MIDIVAL elements.
The 32V ceiling is the figure to watch. These parts are made for 12V and 24V banks; on a 48V system they are the wrong family and a higher-voltage fuse body is needed instead. Within that range the MIDI format handles the currents a vehicle or small off-grid bank actually draws.
The three-way holder is the practical one when a single battery feed has to split into separate protected circuits without building a busbar.
