4.1 Settings
The rated motor current must be set on PKZM0-…/XTPR…BC1NL and
PKZM0-…-T/XTPT…BC1NL by means of the current dial
a
(
page 26) prior to initial commissioning of the motor-protective circuit-breaker.
4.1.1 Test
The motor-protective circuit-breaker is equipped with a testing feature
b
(
Figure 1, page 25). The active PKZM0-…/XTPR…BC1NL and
PKZM0-…-T/XTPT…BC1NL motor-protective circuit-breaker is tripped by
actuating the test release with the help of a screwdriver.
This opens all main contacts and thus removes the output lines from the
voltage source.
DANGER
Faulty devices must not be opened and repaired.
They must be replaced by specialist personnel.
WARNING
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.
