Heater (-R01) for condensation water protection (optional)
Locking mechanisms
To lock vacuum circuit-breakers as a function of the switching position, the spring
charge mechanisms of the vacuum circuit-breaker can be equipped with a locking
mechanism. Mechanical locking mechanism (optional)
A sensing and actuation component (b) on the system side detects the operating po-
sition (CLOSED/OPEN) of the vacuum circuit-breaker.
CLOSED switching
position
If the vacuum circuit-breaker is closed, actuation of the system's interrogation and
actuation component (b) is prevented.
OPEN switching position
If the vacuum circuit-breaker is open, the sensing and actuation component (b) on
the system side actuates, via the stroke (a), the vacuum circuit-breaker's mechani-
cal locking device and reliably blocks closing of the vacuum circuit-breaker.
WARNING
Risk of burns!
Touching the hot heater will cause burns.
Do not touch the heater before it has cooled off.
The heating limits condensation and corrosion of the
vacuum circuit-breaker.
To this end, the heating has to be connected to the sup-
ply voltage (see circuit diagram included with the deliv-
ery).
The surface temperature of theheating is approx.
180 °C.
Power consumption
50 W, rated voltage 230 V AC
