3. Key Integrated Functions

1. Manual motor direct switching
    
   Rotary knob realizes direct on-line start/stop of small and medium motors, integrates isolation disconnect function for maintenance power cut-off.
2. Multi-layer motor comprehensive protection

• Thermal overload delayed trip: Prevent winding burnout from long-term overloading
• Instantaneous magnetic short-circuit trip: Rapid cut-off phase-to-phase short fault
• Phase loss protection: Avoid single-phase operation burning three-phase motors

3. No external fuse required
    
   Integrated thermal-magnetic trip unit, saves cabinet space and simplifies power distribution wiring compared to fuse + contactor schemes.
4. Test maintenance function
    
   Front TEST button simulates overload trip to verify protection circuit integrity without loading the motor.
5. Expandable auxiliary signal feedback
    
   Can be matched with auxiliary contact accessories to output trip fault signal to PLC digital input modules for HMI alarm display.
