Q1 Fuse and K1 Contactor
When selecting a mains contactor and fuses, the continuous current in
the supply leads as well as the starting inrush current must be taken into
account. Several controllers can be operated on a single fuse and mains
contactor. The phase currents and inrush currents of the individual drives
must then simply be added up. If a transformer is used, then the fuses
and contactors must be installed on the primary side.
The Siemens type fuses and contactors in the selection table below are
only examples. Products of equal rating from other manufacturers can be
used.

1. Lead cross sections per EN 60204 – Installation B1 – correction factors not taken into account.
2. With recommended fuses short-term operating loads can be used by the drive for two minutes. If this is needed for
extended periods, then use a bigger fuse.
3. Allocation "2" per DIN IEC 60947-4: easily separable contact welding at contactors are permitted as a result of
short circuits.

Note: To make sure the mains contactor is not overloaded by the
load current in the case of frequent switching o, you rst have
to switch o the drive via the drive enable in the master
communication and then switch o the mains contactor.
