Product Overview

HUW9NE intelligent Air Circuit Breaker (hereinafter referred to as the circuit breaker) is applicable to distribution networks with AC 50/60Hz, rated operating voltage up to 1140V, and rated current up to 6300A. It is mainly used for distribution, feeder, and generator protection, protecting lines and power equipment from overload, undervoltage, overvoltage, current and voltage imbalance, short circuit, and grounding faults. Through load monitoring, regional interlock, and other functions, it ensures the rational operation of the power grid. It can also be used for measuring various power grid parameters such as current, voltage, power, frequency, energy, demand, and harmonics at grid nodes. The circuit breaker can also be directly used for overload, undervoltage, and short circuit protection of motors and generators.

The core components of the circuit breaker adopt an intelligent controller, providing precise selective protection to avoid unnecessary power outages, thus improving power supply reliability, continuity, and safety. It can also be equipped with an open communication interface to achieve "four remote" functions, meeting the requirements of control centers and automation systems.

This series of circuit breakers can be used as isolators when not equipped with an intelligent controller and current transformer.

he circuit breakers in this series can be used for both top and bottom cable entry and are suitable for various low-voltage distribution fields, such as wind power, photovoltaics, factories, and intelligent buildings. They can also be used for the infrequent starting of motors.
