Pain Points in the Application Scenario

~20kA breaking-capacity protection for 100kW AC-side systems. 50kA breaking-capacity protection for 215kW AC-side systems. Required 1.1Ie continuous overload capability and 1.3Un/0.5s high-voltage ride-through performance.

Value of the Solution

NDM3 breakers provide ≥35kA breaking capacity with full 100% rating in both forward and reverse feed, plus dual-insulation cover design for enhanced safety. NDM3A-250V offers ≥50kA breaking capacity, leading the industry. 1.1Ie overload capability and 1.3Ue/0.5s high-voltage ride-through prevent ESS converter testing and operational faults that could pose grid safety risks.
