Overview of 3VA1 as switch disconnectors
3.2.2
Upstream protection of switch disconnectors
Switch disconnectors are not equipped with an integral overload or short-circuit release. For
this reason, a molded case circuit breaker or a fuse must be installed upstream of every
switch disconnector.
The coordination tables given below contain the following information:
● The correct assignment of molded case circuit breakers to the switch disconnectors which
require protection
● The maximum permissible rms short-circuit current kA rms for each combination of
