GSH1 series conversion switchDetailed product description：

GSH1 series conversion switch

The GSH1 series transfer switch is suitable for electrical circuits with AC 50Hz, rated voltage 690V, rated working voltage 220V, rated working current 40A and 63A under the AC-21A usage category, for manual frequent connection, analysis and conversion of AC resistance load circuits. In the AC-3 usage category, in circuits with a rated operating voltage of 380V and rated operating currents of 25A and 40A, three-phase squirrel cage induction motors can be directly started and disconnected during operation.

The relative humidity of the atmosphere shall not exceed 50% when the maximum temperature around is+40 ℃, and higher humidity is allowed at lower temperatures
The average maximum relative humidity of the wettest month is 90%. At the same time, the monthly average minimum temperature for the month shall not exceed+25 ℃, and measures must be taken to prevent condensation on the surface of the product due to temperature changes.
Installation location with an altitude not exceeding 2000m
The pollution level is level 3.
The installation method is installed behind the board.
Installation categories are II and III.

Main performance indicators
rated voltage
The rated insulation voltage Ui is 690V
The rated working voltage Ue is AC50Hz, 220V, 380V.
Rated working system
a) Eight hour work schedule
b) Uninterrupted work system
c) Continue the cycle work system (load factor of 40%, operating frequency of 600 times/hour).
contact resistance
40A contact resistance not exceeding 2m Ω;
The contact resistance of 63A contact shall not exceed 1m Ω.

dielectric properties
The insulation of the transfer switch should be able to withstand a power frequency withstand voltage test of 3000V for 1 minute, and the leakage current should not exceed 50mA.
Action performance
The operating mechanism should operate flexibly and reliably, with accurate positioning angles. The mechanism should ensure that the contacts can only be placed in the closed or open position.
The sequence of actions meets the requirements of the circuit diagram.
Rated connection and segmentation capability

structural type
This product adopts a combination structure, consisting of positioning, limiting, contact series, panel, and handle. The contact system is a bridge type double break point structure, and its on/off is controlled by its respective cam. The positioning system adopts a ratchet and pawl structure. By replacing different positioning ratchet gears and matching them with corresponding cams, the switch can obtain different rotation angles to achieve the corresponding switch states.

Precautions for use
When the switch knob is turned to a fixed position, do not continue to rotate the knob forcefully to prevent damage to the mechanism;
When wiring, it is necessary to strictly follow the instructions in the user manual.
