1) Voltage tolerance +5%.
2) Coordination of short-circuit equipment
according to IEC 947-4/DIN VDE 0660
Part 102:
Type of coordination “1”:
The contactor or starter must not endanger
persons or the installation in the event of a
short-circuit. They do not need to be suitable
for further operation without repair and the
renewal of parts.
Type of coordination “2”:
The contactor or starter must not endanger
persons or the installation and must be
suitable for further use.There is a danger
of contact welding.
3) D-fuse links UN = 500 V, make SIBA.
