1.General
Load isolation (hereinafter referred to as switch) is developed by our companyby introducing advanced technology from Europe. This product has the internationaadvanced level in the late 1990s, and it is an ideal replacement product among similardomestic products. Switch is widely used in power distribution system and automationsystem of construction, power, petrochemical and other industries.Modular design structure, flexible and diverse combination, using glass fiberreinforced unsaturated polyester resin with very high dielectric properties, protectionand reliable operation safety. The operating mechanism is an acceleration mechanismwith spring energy storage and instantaneous release. lt has a double breakpointcontact structure of instantaneous connection and breaking, which has nothing todo with the speed of the operating handle. The switch has a variety of structuresand operation modes. There are windows for directly observing the on-off status othe contact, inside, outside and behind the cabinet, front and side operation, andwiring in front of and behind the board.
The switch has beautiful shape, novel, simple, small volume and full function.
which is the best choice among the similar products.
The product has obtained 3C certification.
2.Application
Load isolation switch is mainly used for AC 50 Hz, rated voltage 660V, DC ratedvoltage 440V, rated current 3150A. lt is used for isolation of infrequently connectingand breaking circuits and lines
3.Product features
The acceleration mechanism of instantaneous release of spring energy storagerealizes fast on or off (13.8m/s), which is independent of the speed of the operatinghandle, which greatly improves the ability of extinguishing arc.The shell made of glass fiber reinforced unsaturated polvester resin has good flameretardant, dielectric,carbonation and impact resistance
The parallel double breakpoint contact has the function of self cleaning.All contact materials are copper silver alloy, with two separate contact surfacesThe isolation distance is large.
When in "O" position, the handle can be locked with three locks at the same timeso as to avoid misoperation reliably。
4.Meet the standard

5.Usage environment
Load isolation switch can operate under the following conditions:Altitude not more than 2000m;
The ambient temperature shall not be higher than 40℃, not lower than -5℃, andthe relative humidity shall not more than 95%;The environment without any explosive medium;The environment without any rain or snow attacking.
Note: lf the product is expected to be used in the environment where temperatureis over 40℃ or below-5℃~45℃, user's shall tell it to the manufacturer.
6.Electrical and mechanical properties of 63 ~ 3150A
7.63~3150A Load isolation switch
Load isolation switch can be divided into 7 specs from 63A to 3150A, it is thebasic type of module design, it has three poles and four poles (three poles switchneutral pole), applied to make and break circuit or electric isolate, over 1000A is only
for electric isolation.Symbol window on front face indicates the contact on-off state.According to the needs, the rear observation window can be provided to directlyobserve the contact on-off status and window style. See operating load isolationswitch behind 160A~1600A/H cabinet.
It can be equipped with two sets of auxiliary contacts.
It can be equipped with cable insulation cover.
8. Operation mode
9.63~100A Load isolation switch
63A ~ 100A is suitable for making and breaking circuit or electrical isolation.63A ~ 100A has three poles and four poles (three poles switch neutral poles)It can be equipped with two sets of auxiliary contacts as required.It can provide inside and outside operation of side cabinet as required.
