MQ2 series dual power automatic transfer switch is one of adopted inernational ATSE technology developed by our company.It is suitable for power supply system with rated insulating voltage is AC 800A,rated working voltage is AC690V, and below DC250V,and AC 50HZ/60HZ,rated working current is 20A-5000A of two-path.The transfer switch and the matching intellect display,they are main used for high building,the post and communication, coal mining,shipping,military facilities industrial assembly line etc the situation of satisfy the higher requires of reliable power supply, the products have reliable performance,small size and easy operation etc features
Attention:It must not do the test of insulating stand voltage for the quality guarantee.
Environment conditions for operation and installation:
1.Ambient temperatures:-5ºC-+40ºC, and average temperature in 24 hours below +35ºC(except for special orders)
2.Elevation of installation site:≤2000m
3.Pollution protection: 3 grade
4.The breakers used on ships and in humid tropical area can work normally without influence of humid air,salt fog and mildew.
5.The breakers used on ships can operate reliably under normal vibration.
6.The breaker should be installed according to stipulations on operating manual.For breakers in common use,the vertical gradient is not more than 5ºC ,for that used on ships,the vertical gradient is not more than 22.5ºC.
7.The breaker should be put in the place where there is not any explosive medium and conductive dust and no gas which would corrode metal or destroy the insulation.
