Product description
Typical applications for draw-out versions of 3VA molded case circuit breakers are
installations in which inspections and overhauls need to be carried out at regular intervals
and, for reasons of safety, clear visual evidence of safe electrical isolation of plant sections
must be provided at short notice so that work can commence. Draw-out versions of 3VA
molded case circuit breakers are also suitable for applications which require that molded
case circuit breakers or switch disconnectors can be replaced very rapidly when necessary.
In the draw-out version, the 3VA molded case circuit breaker is supported by the side walls
of the draw-out unit and can be moved into three defined positions by rotation of a crank
handle. The current breaker position is indicated by the breaker status indicator.
