This starter is specifically designed for coal mines containing explosive gas (A-burning) and coal dust. It enables remote control of soft starting, stopping, and reversing operations for mining explosion-proof three-phase squirrel-cage asynchronous motors. The system provides comprehensive protection for both the motor and its wiring, featuring:
Leakage lockout: Built-in leakage detection using DC detection method, eliminating the need for external leakage plug-in components.
Bypass monitoring: Provides real-time monitoring in both direct start and soft start states for comprehensive motor protection.
Communication function: Standard configuration includes communication components with support for customization and multiple standard bus protocols. Factory default setting uses Modbus-R Tu protocol for easy group control technology implementation.
