Switches and push-buttons
Rotary switches
Features
Photo 2 shows the front view of the rotary switches.
The main characteristics are printed in the upper
part of the device
1 . These are:
- Rated current
- Operating voltage
- 6-digit ordering code
Related to the switching capacity, versions in 32A,
40A and 63A exist.
All devices can be used up to 415V.
The Pozidriv terminals
2 are clearly marked, are
all captive and can be sealed by means of a
terminal cover.
The disconnect function is visible at all times
by means of the handle.
By using the shaft extension, the handle itself can
be mounted on the door of an enclosure, while
the switch itself can be mounted on the DIN-rail
or panel (photo 3).
Two handles are available: a standard (black,
see fig.1) and an emergency handle (red, see fig.2).
Important
:
In case the handle is mounted on the door, the
panel can only be opened when the handle is in
the OFF-position. The emergency handle can be
sealed by means of up to 3 padlocks.
Text for specifiers-The rotary switches all have the
CEBEC and KEMA approval mark following IEC
947.3
- Due to its construction, the rotary switch can
securely interrupt and as such is a disconnect
switch. This, together with the high short-circuit
resistance and the visible contact status, makes it
possible to use this switch as a main switch,
- The housing is made of thermoplastic material
with a high creepage-current resistance
- The movable contacts of the switch are operated
as a paralel bridge with double interruption per
pole. The short-circuit resistance is very high
- The rotary switches all have a width of 4 modules,
- Shaft extensions with standard and emergency-
handles are available
- The rotary switches can be padlocked in the off-
position
- The terminals can be sealed by means of a
terminal cover
