1. Altitude: below 2000m;
2. Ambient air temperature :-25ºC~+40ºC;
3. Relative humidity: the daily average is not more than 95%, the monthly average is not more than 90%;
4. The surrounding air should be free from corrosive or flammable gases, water vapor and other obvious pollution;
5. No frequent violent shaking.
When the isolation switch is switched on, it is operated with an insulating hook. The insulating hook hooks into the locking hook of the isolation switch, pulls the locking hook to the opening direction, unlocks the self-locking device and drives the connected conductive plate to rotate to realize the opening action. When closing, the insulating hook sticks against the locking hook of the isolation switch and drives the rotating shaft to rotate the connected conductive plate to the closing position. At this time, the self-locking device locks the isolation switch in the closing position.
This type of isolation switch can be installed on the pillar, wall, ceiling, cross frame or metal frame, can also be vertically installed, inclined installation, but the installation position should be so that when the contact knife is opened, it tends to the lower.
