SH6C series quick closing automatic switchDetailed product description：

SH8C-1000V, 2500A quick closing automatic switch

Purpose and conditions of use
Suitable for rated voltage DC1000V and below, rated current 2500A and below. When there is a fault in the power system, the main bypass protection is for overcurrent in the AC/DC hybrid transmission grid. When the DC transmission operates on a single pole ground, the ground pole current flows into the AC system through the neutral point of the transformer, causing varying degrees of impact on the AC transmission system. This switch can effectively suppress the DC current at the neutral point of the transformer, ensuring the safe and stable operation of the transformer and AC system.

Normal usage conditions
Altitude not exceeding 2000m
The ambient air temperature is between -5 ℃ and+40 ℃.
Atmospheric conditions: The average maximum relative humidity of the wettest month is not greater than 90%, and the average minimum temperature of that month is 25 ℃.
The pollution level of the switch is PD3 in a medium without explosive hazards and without gases and dust (including conductive dust) that can corrode metals and damage insulation.
The inclination of the corresponding horizontal plane during installation shall not exceed 5 ℃.
