GGD AC LOW‑VOLTAGE DISTRIBUTION SWITCHGEAR is a new‑type low‑voltage switchgear designed in accordance with the principles of safety, economy, rationality and reliability. Featuring high breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong serial performance and practicality, novel structure and high protection degree, it can be used as an upgraded replacement for conventional low‑voltage complete switchgear assemblies.
It is applicable to distribution systems with AC 50(60) Hz, rated operational voltage 380 V(400) V and rated operational current 1000 A ~ 3150 A. It is used for electric energy conversion, distribution and control of power, lighting and distribution equipment.
