Test
The motor-protective circuit-breaker is equipped with a
testing feature
b
(
Figure 1, Page 24). The active
PKZM0 motor-protective circuit-breaker is tripped by
actuating the test release with the help of a screwdriver. This
opens all power contacts and thus removes the output lines
from the voltage source.
Warning!
Faulty devices may not be opened for repairs and must be
replaced only by suitably qualified personnel.
Vorsicht!
If the motor-protective circuit-breaker is installed at a cool
location (e.g. -5 °C) und the motor is installed at a warm
motor location (e.g. 40 °C), it is possible that there will be
a delayed release
during an overload if the devices are
operated in the lower current setting range.
