PKZ 2 Motor and
System-Protective
Circuit-Breakers
Plug-in trip blocks:
Fast adaption to engineering
changes
Various plug-in trip
blocks allow the PKZ 2 to be
converted in no time at all.
3-pole and 4-pole trip
blocks are available for
motor and system protection.
Differential signalling
clearly indicates the
switching states of the
circuit-breaker.
 
Auxiliary contact
modules, voltage releases or
trip-indicating auxiliary
contacts can be fitted
quickly and easily.
When used in combination
with the PKZ 2 basic unit,
the ZMR-PKZ 2 plug-in trip
block with overload relay
function switches off the
downstream contactor rather
than disconnecting the
circuit-breaker in the event
of a motor overload. The PKZ
2 thus remains switched on
and does not need to be
manually reset.
Locally and remotely:
switching and signalling
PKZ 2 has intelligent
accessories to allow
flexible solutions for a
wide range of communication
tasks. The RS-PKZ 2
electronic remote operator
can be actuated directly,
without any coupling
elements from the
semi-conductor outputs of a
PLC (24 V DC).
With electrical isolation
between CONTROL and LINE, it
can take the power for the
switching process from a
separate power supply (e.g.
230 V 50 Hz).
On the RE-PKZ 2 – the
electronic remote operator
for standard applications –
CONTROL and LINE are
separate inputs, although
they use the same potential
reference. This allows
actuation by low consumption
units, such as control
circuit devices.
