11kv High Voltage Soft Starter For Ac Compressor Motor Cabinet

The MT830 high-voltage solid-state integrated soft starter combines a trolley-type vacuum circuit breaker with the MT830 soft starter, integrating high-voltage switchgear functions for enhanced performance and stability. Specifically designed for AC motor starting and stopping applications, it features:

• Low starting current for reduced electrical stress
• Smooth acceleration profile to minimize mechanical shock
• Extended service life for both motor and starting equipment
