Table 7: Vacuum interrupter stroke
Footnotes:
1.
The vacuum interrupter type des-
ignation is labeled on the vac-
uum interrupter. If the vacuum
interrupter installed does not
match that indicated in this
table, contact the nearest Sie-
mens representative.
2.
If you need assistance achieving
the indicated stroke setting, con-
tact the nearest Siemens
representative.
