Core Protection Features

Advanced Motor Protection

Differential Bimetallic Strip: Accurately detects three-phase current imbalance and overload with temperature compensation for stable protection across wide temperature ranges
Class 10A Fast Tripping: No tripping within 1.05×Ir for 2h; tripping within 1.2×Ir for 2h; approximately 7.2s tripping at 1.5×Ir for rapid motor winding protection
Phase Loss Protection: Quick trip response when any phase current becomes abnormal, preventing motor burnout due to phase loss
Test/Indication System: Built-in test button and trip indicator (T) for fault simulation and circuit verification
Security Features: Front cover with lead seal hook to prevent accidental parameter adjustment
