SIRIUS System Manual
3-126
GWA 4NEB 430 0999-02b
3RT15 contactors, 4-pole (2 NO contacts + 2 NC main contacts)
1) Corresponds to section from IEC 60 947-4 (VDE 0660 Part 102):
Coordination type "1":
The destruction of the contactor and the overload relay is permissible. The contactor and/or overload relay must be replaced, if necessary.
Assignment "2":
The overload relay must not be damaged. Contactwelding on the contactor is permissible, if it can be easily separated again from the contactor.
