Photovoltaic Grid-Connected Molded Case Circuit Breaker

Residual current reclosing circuit breaker with enhanced PV-specific protection, dual-mode communication (HPLC/HPLC), and power quality monitoring for power IoT applications. Used to connect PV systems to low-voltage grids, with core functions including anti-islanding protection (independent of inverter), overload/short-circuit protection, harmonic analysis for power quality assessment, and precise measurement of power, voltage, current, and frequency. Compliant with GB/T 14048.2 and Q/GDW 1972.
