Overview
The 3VT switch disconnectors are a derivative of the corre-
sponding 3VT circuit breakers. This has the advantage that they
can be equipped with accessory components in a wide range of
ways.
The only difference between this version of the switch connec-
tors and the circuit breakers is the absence of a release. They
can be used up to a rated voltage of 690 V AC and 440 V DC.
