7 Series
Residual current circuit breaker for AC 50/60Hz circuits (230V single-phase, 400V three-phase), with rated currents from 32A to 125A. Provides earth leakage, overload, and short-circuit protection, and allows infrequent line switching or motor starting.
Designed for 50 Hz, 400 V power systems, this circuit breaker distributes energy and protects against overloads, short circuits, voltage anomalies, and phase loss. It measures current, voltage, power, and energy, and supports RS-485, PLC, Bluetooth, and HPLC communication (compliant with DL/T 645, DL/T 698.45). It features hot-swappable controllers, terminal temperature monitoring, and remote control functions, meeting GB/T 14048.2 standards.
Residual current circuit breakers with automatic reclosing for 400V, 50Hz low-voltage grids (50A–630A, 50mA–800mA residual current). Integrates overload, short-circuit, residual current, over/undervoltage, phase loss, neutral loss, and lightning protection, plus reclosing. Also available as prepayment meter external breakers. Compliant with GB/T 14048.2, GB/T 32902, Q/GDW 1365.
