1.The elastic-acceleration acceleration mechanism for instantrelease realizes the rapid making and breaking(13.8M/S),having no relationship with the speed of the operating handle,and increasing greatly of exingushing electric arc.
2.The shell made of unsaturated polyester resin reinforced by glass fibre possesses excellent performance of flame resistant,dielectic performance,safe opration,resist carbonic performance and resist impact perdormance.
3.Parallel double gap contact posseesses self deaning functions.
4.ALL the contace materials are copper alloy plaetd with silver,and possess two separation contace surfaces.
5.Large insulation distance.
6.Be on "O",the products can lock the handle with three lockes at the same time and thus can aviod error operation.
LM(HGL)series load isolation switch can work reliably under the folwing condition
1.Height abovt sea level does not exceed 2000m
2.Ambient temperature is not higher than +40℃~and not lower than-5℃,relative humidity is not lager than 95%.
3.No explosive dangerous medium environment
4.No rain and snow attack environment
NOTE:If the load isolation switch is exoected to be used in the conditon that the ambient temperature is highter than +40℃ or is lower than -5℃~-45℃ cuetormers should inform to the manufactory
1.7 specifications of LM(HGL)load isolation switch from 63A to 315A Basic of modularized design,possesses three poles,and four poles(3 poles+on and off neutral pole).It is suitable for electric isolation.Switches over 1000A are only suitable for electric isolation.
2.Mark winkow is set in the front side to indicate the on andoff state of the contact
3.Rear observation window can be provided according to the demand to observe directy the on and off state of the contact
4.For window pattern,refer to the back oprational load isolation switch,LM(HGL)-160A~1600A/H.
5.Two sets of auxiliary contacts can be assembled according to demand.
6.The eletric cable insulating cover can be assembled.
