Draw-out technology
4.4.6.1
Typical applications for draw-out units for the 3VA UL molded case circuit breaker range are
installations in which inspections need to be carried out at regular intervals and a visible
electrical isolation is required by removal of the circuit breaker, which must be implemented
quickly. In addition, draw-out units for the 3VA UL molded case circuit breaker range are
used when a very fast replacement of molded case circuit breakers or molded case switches
is required.
In the case of draw-out technology, the 3VA UL molded case circuit breaker is mounted on
the side walls and can be moved into three defined positions by turning the crank handle.
The current breaker position is indicated by the breaker status indicator.
