High Voltage Custom Soft Starter In Electric Power System
Product Overview
MT830 high-voltage solid-state integrated soft starter, on the basis of MT830 soft starter, add a trolley-type vacuum circuit breaker, integration of high-voltage switchgear functions, performance is more integrated.
Based on MT830 soft starter, MT830 adds handcart type vacuum circuit breaker and integrates the functions of high voltage switchgear, which makes the performance more integrated and stable.
Model MT830 is specially designed for the starting and stopping of AC motors as running power.
Typical applications
Widely used in squirrel cage asynchronous motors in electric power system, machinery manufacturing, cement production, metallurgy, mining, oil extraction, chemical industry, water treatment and other industries.
As a three-phase voltage 3kV-15kV medium and high voltage As a three-phase voltage 3kV-15kV medium and high voltage motor starting, control, protection, soft stop.

Operating environment
The altitude of the installation place is not more than 1000m above sea level; if it is more than 1000m above sea level, the capacity should be reduced;
The ambient temperature is -10～40℃, above 40℃, it should be used at a reduced capacity, and the current should be reduced by 2% for every 1℃ above; ● The ambient humidity is ≤95%.
Ambient humidity ≤95%RH, no water condensation;
●Indoor without corrosive gas that destroys metal and insulating materials;
● No direct sunlight, dust, flammable gas, oil mist, dripping water or salt;
● Indoor installation upright installation.
