The frequent misoperation of the RCBO presents safety risks. An upgrade to Type A+6mA or Type B residual current protection is necessary to improve safety.
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. VPM385-40/3N+NPG-1UN and VPH888-12.5/3P+1P (T1+T2) SPD surge protectors realize professional surge and lightning protection for the PCS converter, effectively avoiding device damage caused by grid surges and lightning strikes. 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.
