This external circuit breaker is designed for prepaid energy meters, offering intelligent features including meter control with status feedback, fee control (tripping on power cutoff, auto-reclosing after payment), auto-operation (tripping on outage/over/undervoltage/phase loss, auto-reclosing on restoration), PV grid-tie support (“ON with grid, OFF without grid” logic), and comprehensive line protection (short-circuit, overload, over/undervoltage, phase loss). Compliant with GB/T 10963.1 and Q/GDW 11421-2020.
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.
IoT-enabled circuit breaker for AC 50Hz distribution protection (up to 400V, 800A, 1000V insulation).
