GP3P Series Photovoltaic Grid-connected Circuit Breaker
The GP3P Series Photovoltaic Grid-connected Circuit Breaker is designed for automatic grid connection in distributed renewable energy generation applications. It provides islanding protection and automatic reclosing for distributed power sources.
Overvoltage, undervoltage and voltage-loss protection provide islanding protection. The breaker automatically reconnects when the main grid recovers. Its compact design combines high breaking capacity, reliable operation, stable performance, convenient installation and a user-friendly interface.
The product meets the requirements of State Grid Q/GDW-2013, Technical Specification for Dedicated Low-voltage Circuit Breakers for Distributed Photovoltaic Grid Connection.
