7 Series Residual Current Circuit Breaker
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.
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.
Engineered for low-voltage distributed PV systems, this all-in-one breaker integrates an electric operating mechanism, intelligent controller, and MCCB functions. It delivers comprehensive protection against overcurrent, short circuit, phase loss, and voltage anomalies (over/under/zero voltage), ensuring safe and reliable grid integration. Complies with GB/T 14048.2 and Q/GDW 1972-2013.
