UEB-63(100)N series intelligent meter dedicated miniature circuit breaker is a limited-current high-breaking capacity miniature circuit breaker with overload, short circuit and intelligent undervoltage release function. It is suitable for AC 50Hz/60Hz, rated voltage of 230V/400V, rated current not exceeding 100A circuits, and can remotely control circuit disconnection or automatic signal control disconnection, and at the same time protect the circuit against overload and short circuit. It can also be used for infrequent switching operations.
This manual describes the UEB-63(100)N series micro circuit breaker designed for smart electric meters. It outlines the product’s overload, short‑circuit, and intelligent delayed‑trip functions, and lists the applicable standards (GB10963, IEC60898).\n\nThe document includes technical parameters, wiring diagrams, installation conditions, ordering information, and service guidelines. It is intended for engineers and installers who need to integrate the breaker with single‑phase or three‑phase distribution systems and smart meters. This manual is written in Chinese.
