Description of ZW32-24F Series Outdoor High-voltage (Intelligent) Vacuum Circuit Breaker
The ZW32-24F Series Outdoor High-voltage (Intelligent) Vacuum Circuit Breaker is a high-performance, intelligent outdoor power distribution device, specifically developed for three-phase AC 50Hz power systems with a rated voltage of 24KV. It integrates advanced vacuum arc-extinguishing technology and intelligent control modules, upgrading the traditional outdoor high-voltage circuit breaker with enhanced intelligence, reliability, and operational flexibility.
As a core protection and control component in medium-voltage distribution networks, it is mainly used to switch on and off load currents, overload current,s and short-circuit currents in power systems. Its rapid fault response capability can promptly isolate faulty circuits, effectively preventing damage to power equipment and avoiding large-scale power outages, thus ensuring the stability and continuity of the power supply.

Designed exclusively for outdoor operation, the breaker features a rugged structure and excellent environmental adaptability, capable of maintaining stable performance in harsh outdoor conditions such as extreme temperature changes, high humidity, dust, and UV radiation. Its intelligent design also facilitates remote monitoring and control, making it a cost-effective and efficient solution for modern distribution networks.
