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.
