5. APPLICATION CONDITIONS OF
THE DEVICES
5.1. Short-circuit protection
To protect against short-circuits, either a fuse (max. 3 x Ib in accordance
with IEC 60127-2-1) must be connected upstream of each magnet
according to the rated current of the magnet, or a motor protection
switch with short-circuit and thermal quick release (set to rated current).
If rated currents of the magnet are very low, the fuse with the lowest
current value is adequate in accordance with the stated IEC standard.
This fuse may be housed in the associated supply unit or must be
connected separately upstream. The rated voltage of the fuse must be
equal to or greater than the indicated nominal voltage of the magnet.
The breaking capacity of the fuse insert must be equal to or greater
than the maximum short-circuit current accepted at the installation
location (usually 1500 A).
The operator must guarantee short-circuit protection for models A and
L of the electromagnet. The fuse is installed in the terminal box of the
device for model K of the electromagnet.
For a more detailed description of models A, L and K see
chapter "6. Technical Data".
