FAR6B-GD100B Automatic Circuit Breaker Specially for Grid Connection
The FAR6B-GD automatic grid-connected dedicated circuit breaker provides islanding protection and automatic reclosing function for distributed power sources. The product is suitable for all kinds of distributed new energy power generation automatic grid-connected occasions. This series of products has small size, high breaking, reliable action, stable performance and good human-computer interaction interface, simple installation, island protection through over-under-voltage and loss of voltage protection, and automatic grid connection when the main power grid is restored. It meets the requirements of State Grid Q/GDW1972-2013 "Technical Specifications for Distributed Photovoltaic Grid-connected Special Low-voltage Circuit Breakers". The product realizes island protection and automatic grid connection for the distributed power grid in unattended occasions.
Functional structure features
The under-voltage and loss-of-voltage protection functions are integrated with the operating mechanism
The modular structure is combined into a whole, and the 35mm standard guide rail is fixed, which is convenient for customers to quickly install, repair or replace
The L7 miniature circuit breaker platform is selected, and the opening and closing action is fast and reliable, the temperature rise is low, and the operating force is small
With manual/automatic transfer switch, safe and reliable
The circuit breaker has a built-in integrated axis to realize the linkage of each pole, and the synchronization of opening and closing is good
Low standby power consumption, power saving, low-carbon and environmental protection
