To be equiped with aM or gG (gL - gl) type fuse cartridge without striker, with or
without fuse blowing indicator.

Isolation of all poles is guaranteed for the 2P, 3P, and 3P+N versions during
factory assembly.
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.).
(1) The neutral pole comes equipped with a locked tube.
