Structure Features
1. The switch contactor is a straight motion mechanism with double-braking contacts.
2. Auxiliary contacts (F3-d1, F3-X1) can be installed on the sides of the device. Meanwhile, interlocked contactors can be achieved by mounting an interlock mechanism on the apparatus's sides.
3. A voltage suppressor, time delayer, and other functional modules can be connected to the coil terminals.
4. On the top of the device, auxiliary contacts (F3-d, F3-X, F3-d2, F3-X2) and air time-delay terminals (SK4-2d or SK4-3d) can be installed.
5. Three contactors and one air type time-delay terminal can make up a star delta starter.
6. In addition, a thermal overload relay and an AC contactor can make up an electromagnetic starter to protect the electrical circuit from overload damages.
Note: F3-d2 and F3-X2 auxiliary contacts can only be connected with products between GSC3-40 and GSC3-95 models.

Working and Installation Condition
1. Ambient temperature: -25℃~+60℃
2. Elevation: ≤3000m
3. Relative humidity: ≤ 85% (at the maximum ambient temperature +40℃); Special measures should be taken to avoid or remove condensation caused by temperature changes.
4. Pollution grade: Grade: 3
5. Installation class: class Ⅲ
6. Installation method: In addition to standard screw mounting, GSC3-09 to GSC3-38 models are also applicable for 35mm track mounting, and GSC3-40 to GSC3-95 models are applicable for 75mm track mounting.
7. Installation tilting angle: ±25°
