T
Rotary Switches up to 315 A – Flexible for All
Switching Functions
The
modular system is particularly flexible and enables
a wide range of different combinations and types.
T
rotary switches are available for rated
uninterrupted currents from 10 A to 315 A in three
basic designs:
-
Flush mounting (front fixing)
-
Centre mounting (base fixing with coupling)
-
Surface mounting (insulated enclosure).
Each of
these basic forms offer several variants. Mounting
in central control or distribution panels and as
main switches or main switches used as
Emergency-Stop devices to IEC/EN 60 204-1, VDE 0113 Part 1.
T
rotary switches can be used in a wide range of
applications as:
Auxiliary circuit control switches
T
rotary switches for auxiliary circuits simplify
command functions at central locations. For example,
a particular program can be selected from a control
station, thus saving time and providing a clear
central overview of the production process.
Coding,
step, series and manual/automatic switches are
common applications for auxiliary-circuit control
switches. T0 rotary switches and TM mini rotary
switches are particularly suitable for this purpose,
with space-saving installation.
With up
to 22 contacts and 12 switch positions, the T0
handles a wide range of switching tasks. The small
dimensions of the TM make it ideally suitable for
use in conjunction with the
RMQ-Titan command and
signalling range.
Maintenance, repair and safety switches
A
number of padlocks may be fitted in the Off
position. Disconnection is therefore visible, and
the equipment cannot be switched on again.
On-Off switches
T
rotary switches and P switch-disconnectors provide
reliable service for lighting and heating systems,
motors etc. in accordance with utilisation category
AC-3, as well as in applications requiring a high
switching capacity and switching frequency.
Other
typical applications for T rotary switches include:
-
Star-delta motor starting circuits with or without
reversing and with or without a contactor
interlock.
-
Motor speed variation (tapped windings) for two,
three or four speeds, with or without reversing.
-
Switching a load between two power systems, or
connecting one power system to two loads using the
same switch.
-
Three-phase motor starting on a single-phase power
system with a capacitor.
-
Stepped switching for any required number of
loads, with or without a zero position.
-
Ammeter switching for measurement directly or via
current transformers.
