1.USAGE
GL series lsolator(Load isolation switch)apply to AC 50Hz,rated voltage below 400V.Rated current is 3150A.It is suitable for connecting and breaking the infrequent electric circuit or electric isolation in power system.This product comply with IEC60947-3.

2.ENVIRONMENTAL CONDITIONS

□Altitude not exceed 2000m.

□ Ambient air temperature is not higher than +40℃ and not lower than-5℃.And the average temperature value of 24 hours is not higher than+35℃.
□ When the maximum temperature up to+40℃,air relative humidity should not larger than 50%.In the lower temperature,it allows to have a higher relative humidity,but should take measure when temperature occasionally change or turn the condensation.
□No explosion hazard medium environment.

□ Pollution is 3 class.

4.STRUCTURAL FEATURES
4.1 Switch adopt elastic-accumulating mechanism for instant release realizes the rapid making and breaking.Have no relationship with the speed of the operation handle and increasing greatly the capability of extinguishing electric arc.
4.2 The shell made of unsaturated polyester resin reinforced by fiberglass possess excellent performance of flame resistant,dielectric performance,safe operation,resist carbonic performance and resist impact performance.
4.3 Switch have 3P and 4P(3P+Neutral pole)
4.4 Mark window is set in the front side to indicate ON and OFF state of contact.
4.5 Operation handle can installed directly in the middle of the switch is inside operation.And also can additional longer handle installed outside of the distribution boxdoor.It calloutside operation.
4.6 According to the need,can supply normal open and normal closing auxiliary contact and install special base board,the front and behind connection type,to meet client need.
4.7 When in disconnect position"O",can use two or three locked the handle to avoid misoperation.

5.STRUCTURE AND CHARACTER
The Switch shell is manufactured with unsaturated polyester resin reinforced by fiberglass plastic(DMC).Spring energy storage and Speed institutions can quickly achieve connected with the breaker or disconnected with the break The structure of the contact is parallel double breakpoint two separate head,and ensure the contact pressure by shape spring;Switch can automatically determine the limit position of on and off,and has the obvious On-off tag to indicate the on and off position.

6.TECHNICAL PARAMETER
6.1 GL series isolation switch's technical parameter(See table 1).
6.2Outside operation,behind box operation,behind board connection,isolation switch'stechnical parameter all meet relative GL.
6.3 GLZ Manual changeover switch's technical parameter is meet relative GL.
