Permissible mechanical interlocking combinations
IEC 60947-6-1 contains the requirements for electrical and/or mechanical interlocking for
automatic transfer switching equipment (ATSE), which serves to prevent possible short-
circuits due to the coupling of non-synchronized networks. The circuit diagrams below for the
Siemens switching devices show the electrical interlocking that is required in order to comply
with the requirements of IEC 60947-6-1. Customers who wish to have a mechanical
interlocking in addition to, or instead of the electrical interlocking, can obtain the possible
combinations of Siemens breakers from the table below. For detailed information, please
refer to the corresponding operating manual for the product.
