Production Instruction:
LW28 Series Universal changeover switch mainly used for AC 50Hz, rated voltage up to 380V and below, DC voltage up to 220V, rated current to 160A electrical circuit for manually infrequent making or breaking the circuit for the purposes of control and conversion ,can also controlling three-phase asynchronous motors and circuit directly as the purposes of master control and measurement. The products widely used, instead of the various national switch, can be used as the circuit control switch, measuring equipment switches, motor control switches and the master control switch, and welding machine switch and so on. Compliance with standards: The changeover switch use to the main circuit switching and direct control comply with GB14048.3-2001 The changeover switch use to master control comply with GB14048.5-2001
LW28 Universal Changeover Switch :
a.LW28 series rotary switches applied to circuits of AC 50Hz with working voltave up to 440V and rated working current up to 100A.
b.LW28 is suitable to control:air-conditioner,water pump and ventilating equipments,and AC motors with small power..
c.LW28 series rotary switches have six current ratings:20A,25A,32A,40A,63A,80A and 100A.
d.LW28 series has the finger protection terminals,which offers an extra advantage.
e.LW28 series switches has Larger insulation distance,quick disconnectinvg response.And is a good choice For DC circuits.LW 30 has additional contact which enable us to install the contact separetely.
f.LW28 series rotary switches switches comply with:GB/T 14048.3,and IEC 60947-3.
