4.1Ambient air temperature: -25°C – +55°C;
4.2Installation location elevation: less than 2000m;
4.3Pollution degree: 3;
4.4Utilization category: AC33iB;
4.5Installation method: horizontal or vertical.

2.1Good installation performance.
2.2Using the double composite contact, horizontal structure, micro motor pre storage and micro control technology, which basically realize the zero flying fox (no arc shield)
2.3The reliable mechanical interlocking and electrical interlocks make a higher security.
2.4Zero crossing technique, in case of emergency, which can be forced the ATS stop at the zero position (simultaneously cut off two power supply).
2.5The obvious functions of on-off position indication, padlock, etc., realize the isolation between the power supply and the load.
2.6High reliability, over 10000 times of service life.
2.7Good electromagnetic compatibility, strong anti-interference ability, no interference to the outside.
2.8High degree of automation.
2.9With the multiple input /output interfaces, so it is convenient for remote PLC control and automation system.
2.10Do not need to be connected with any control components.
2.11Nice appearance, small size and light weight, and it is controlled by the different logic control board and logic, to operate the inside built motor and gear box to make sure the position of the ATS.
