Residual Current Operated 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.
IoT-enabled circuit breaker for AC 50Hz distribution protection (up to 400V, 800A, 1000V insulation). Provides comprehensive protection (overload, short-circuit, residual current, over/undervoltage, phase loss) and real-time monitoring of current, voltage, power, energy, and terminal temperature. Features power line carrier communication and network topology identification, supporting smart grid operation and maintenance. Compliant with GB/T 14048.2 and DL/T standards.
