A handle that can padlocked into both positions is
available request. order prevent operating mistakes, they can
be equipped with various locking devices. There is
also lock frame available, which can provided with
key locking for Castell, Lowe&Fletcher Ronis. Furthermore, connecting the
interlocking coil the control unit the rectifier bridge,
the breaking full DC-load can prevented.
All handles the enclosed switches can equipped
with padlocks, which prevent the operating O-position.

Connecting the auxiliary contacts
to the rectifier bridge control
circuit recommended, because
it enables the currentless

This means that the switch shall not operated when

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
