32A 3P 1 position LW26 series Rotary Cam Switch Changeover Switch
Description:
The LW26 series Rotary Cam Switch mainly applies to 440V and below,
AC 50Hz or 240V and below DC Voltage. For breaking and closing,
change-over of circuits under Infrequent manual operation. And the
typical application are: control switch of 3 phase motors, control
switch gear, control switch of instruments, and change-over switch
of machinery and welding machine.
General Features:
1. Wide range of function for switching, it has
20A,25A,32A,63A,125A,160A,315A
2. Capability for switching of resistive, or inductive, or mixed
loads.
3. The most economical way for switching electrical loads.
4. Made of the best materials with high mechanical, electrical and
thermal resistance.
5. Fast and easy installation and wring.
6. Capability to produce special Cam Switches based on customer
requirements.
7. 20A-160A items of Rotary Cam Switch can also be equipped with a
protective waterproof housing(IP65).
Advantage:
- LW26 series Rotary Cam Switches have the characteristics of small
size, multi-function, compact structure, exquisite material
selection, good insulation, flexible conversion operation, safety
and reliability, and novel appearance.
- LW26 series Rotary Cam Switches have many different types of
operation handle to choose by
customer(“R”,”I”,”R2”,”B”,”F”,”L”,”P”and “K” types)
