■
Overview
The devices are used for the switching of lighting, motors and
other electrical devices.
The rated currents of the range are 20 to 125 A.
There is a compact series of space-saving devices with up to
4
NO contacts in a single MW available for rated currents 20 and
32
A.
The ON/OFF switches in the rated currents (32 to 125 A) can be
used as switch disconnectors according to IEC/EN 60947-3.
A special version of the ON/OFF switch with rated current 63 A
is available for use in meter cabinets. This version can be locked
in the OFF position using a special key. The clamping screws are
mechanically covered so that they are no longer accessible.

Benefits
•
The switches can be retrofitted with auxiliary switches without
the need for tools.
•
Uniform auxiliary switches for miniature circuit breakers and
switches. So no need to stock-keep additional components.
•
Clear and visible conductor connection in front of the busbar
for safe and easy mounting.
•
The infeed can be either from the top or the bottom as the
terminals are identical. This simplifies connection.
•
The 20 and 32 A switches can be bus-mounted with each
other or with 5TE4 8 pushbuttons, 5TE5 8 light indicators or
5
TT4 1 remote control switches and 5TT4 2 switching relays.
This saves time and space.

•
Spacers can be used as a compensating element and have a
width of 0.5 MW. They come with an integrated wiring duct for
the insertion of conductors.
•
Two reciprocally installed spacers thus offer space for large
conductor cross-sections up to a 15 mm diameter. This
simplifies cable routing in the distribution board.
•
The handle locking device prevents undesired manual on and
off switching. This increases operational safety.
•
The handle locking device is a universal accessory for all
switches and miniature circuit breakers. This simplifies
logistics.
