Core Protection Features
Differential Bimetallic Strip
Accurate three-phase current imbalance detection with built-in temperature compensation for stable protection across wide temperature ranges.
Class 10A Fast Tripping
No trip at 1.05*Ir for 2h; trips within 2h at 1.2*Ir; trips in ~7.2s at 1.5*Ir for rapid motor winding protection.
Phase Loss Protection
Immediate tripping on abnormal phase current to prevent motor burnout from phase loss conditions.
Test & Indication
Built-in test button and trip indicator (T) for circuit verification; red stop button for forced contact disconnection.
