Note!
ƒ
All fuses specified here only have the purpose of disconnection after a short
circuit. For cable protection specific fuses must be used.
ƒ
In the following tables the rated currents of the Lenze fuses are listed. If
other fuses are used, other fuse currents and cable cross−sections may
result.
ƒ
We recommend using fuse holders with a signalling contact. Like this, the
entire drive system can be switched off (inhibited) when a fuse fails.
ƒ
Always fuse DC cables using 2 poles (+U
