The complete set of soft start control cabinet is composed of a soft starter as the main control body and corresponding specifications of contactors to achieve the soft start and soft stop functions of three-phase AC squirrel cage asynchronous motor. It also has multiple protection functions such as overload, overcurrent, phase loss, three-phase imbalance, overvoltage, undervoltage, etc. Widely used in industries such as metallurgy, petroleum, chemical industry, machinery, water supply, municipal engineering, cement, etc., it is an ideal replacement product for traditional Y/△ starting, self coupling voltage reduction starting, and other industries.
The complete set of soft start control cabinet mainly reduces the starting current of the motor, reduces the distribution capacity, avoids capacity increase investment, reduces starting stress, and extends the service life of the motor and related equipment. It has multiple starting modes and a wide range of current, voltage, and other settings, which can adapt to various load conditions. Equipped with a main circuit breaker and a bypass contactor, it is used to achieve multiple control and protection of the motor. At the same time, there are start and stop buttons, operation, stop, fault indication, and reserved remote control contacts. Remote control contacts include start stop input contacts, operation output contacts, fault output contacts (all passive relay contacts), and computer communication interfaces for upper computer control and management.
Structural characteristics of the complete set of soft start control cabinet:
The starting time can be preset, and different starting times can be set according to different load types;
One drag multiple functions, one soft start device can start multiple motors in sequence;
The initial voltage can be preset, and different initial voltages can be set according to different load types;
The shutdown methods are divided into soft shutdown and free shutdown;
Equipped with current limiting function, ensuring that the starting current does not exceed the set current value;
Bypass contactor function, after starting, the bypass contactor can be connected;
It has multiple protection functions.
