GSC2-F range switch contactor is designed for use in an AC 50Hz or 60Hz electrical system with rated working voltage up to 660V. Under AC-3 utilization category and rated working voltage of 380V, its rated working current is between 115A and 630A. It is an ideal electrical apparatus for frequency starting and control of AC motors and long distance switching of a power circuit as well.
Auxiliary contacts and air time-delay terminals can be installed on the device to achieve more functions. Meanwhile, a thermal overload relay and an AC contactor can make up an electromagnetic starter to protect the electrical circuit from overload damages.

Working and Installation Conditions
1. Ambient temperature: -5℃~+40℃; daily average temperature ≤35℃
2. Elevation: ≤2000m
3. The relative humidity should be no more than 50% at the maximum ambient temperature of 40℃, while it could be relative higher when the ambient temperature is relatively lower. In the month with the highest relative humidity, the minimum average temperature should be no more than 25℃m, and meanwhile, the month's maximum average relative humidity should be no more than 90%. Special measures should be taken to avoid or remove condensation caused by temperature changes.
4. The AC contactor should be installed on steady surfaces without shaking or vibration.
5. Installation method: screw mounting
6. Installation class: class III
7. Pollution grade: Grade: 3
8. Installation angle: the switch contactor should be vertically installed, and the installation angle tolerance is five degrees.
