Factory outlets East of constant high current heater universal changeover switch 160A motor control switch

The scope of
LW28 series switches are mainly used for AC 50Hz, rated voltage is 380V and below, 220V DC voltage, rated current of 160A in electrical circuits, for manual not frequently connected or by breaking circuit control and conversion purposes, can also be directly controlled three-phase asynchronous motors and use as master control and measurement circuits. Product versatility, replacing national conversion switch can be used as control switches, test equipment, motor control switch, and master control switch, and electric welding machine switches and so on.
Standard: the main circuit and control transfer switch in accordance with GB14048.3-2001.
Master control switch in accordance with GB14048.5-2001.
