All handles the enclosed switches can equipped
with padlocks, which prevent the operating O-position. Electrical
interlocking with push button, which installed the

The bigger safety switches are
DC-20-categorized
This means that the switch shall not operated when
loaded. Although the
safety switch DC-23 utilization
category able break full motor
current (4xIe), using the safety
switch motor controller not
recommended.
A handle that can padlocked into both positions is
available request.
Interlocking
The n. Furthermore, connecting the
interlocking coil the control unit the rectifier bridge,
the breaking full DC-load can prevented.
From I-position to
O-position^fifst
the switch the
main circuit and
then the switch of
the magnetizing
circuit. There is
also lock frame available, which can provided with
key locking for Castell, Lowe&Fletcher Ronis.
The switch disconnectors are
mechanically interlocked that they can be
perated only the right order:
From O-position
to I-position: first
the switch the
excitation circuit
and then the switch
of the main circuit. auxiliary contacts the
utilization category\DC-23 safety
switch have earlybreak feature,
meaning that they open before the
contacts the safety switch--------
Connecting the auxiliary contacts
to the rectifier bridge control
circuit recommended, because
it enables the currentless
operation the safety switch
to OFF-position.o.The operating principle safety switches
There are two switch disconnectors in
DC safety switches: one for the main circuit
and the other for the excitation circuit and
control circuit auxiliary contacts. order prevent operating mistakes, they can
be equipped with various locking devices
