China Universal Transfer Switch Lw26-20/3 Three-Phase Motor Commutation Reversible Reverse Transfer Switch 20A Four-Gear Three-Section, Find details about China Transfer Switch, Cam Switch from Universal Transfer Switch Lw26-20/3 Three-Phase Motor Commutation Reversible Reverse Transfer Switch 20A Four-Gear Three-Section
1.Products Introduction
The LW26 sereies rotary switch mainly applies to 440V and below,AC 50Hz or 240V and below DC circuits.
For breaking and closing,change-over of circuits under unfrequenly 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.
The series comply with the GB 14048.3,GB 14048.5 and IEC 60947-3,IEC 60947-5-1.
The LW26 series have 10 current ratings:10A,20A,25A,32A,40A,63A,125A,160A,250A and 315A.
They were designed for multiple functions,wide variety of applications.
The LW26-10,LW26-20,LW26-25,LW26-32F,LW26-40F and LW-60F have finger protection terminals.
LW26 series rotary switch are an excellent substitute for LW2,LW5,LW6,LW8,LW12,LW15,HZ5, HZ10,and HZ12.
The LW26 series rotary switch has two derivatives,LW26GS Pad-lock type and LW26S Key-lock type.
Both of them are applicable in circuits when an physical control is required.
We can equip protective box(IP65) for 20A to 250A.
