Operating Instructions
Installation type
For the VT630 the fixed-mounted circuit breaker is the basic
version. This can be converted very easily into a plug-in version
with the aid of the appropriate mounting set. This set contains
blade contacts, a locking pin and terminal covers for the plug-in
version. See Fig. 5 for VT630 plug-in version pictures and
dimensions.

CAUTION
If an undervoltage release has been installed, it must be
energized, otherwise the circuit breaker cannot be closed!
After a tripping operation due to thermal overload, the circuit
breaker can only be reclosed after a cooling period of several
minutes.
