to be equipped with aM or gG (gL-gl) type fuse cartridge without striker
The general purpose fuse
(gG fuse)
provides overload and short-circuit protection.
The fuse for motor application
(aM fuse)
only provides short-circuit protection. It is
used for protection of loads with a high peak current (motors, transformer primaries,
etc.).
