Products Description

 

Our 3.3 kv circuit breaker is a high-reliability protection equipment specially designed for 3.3kV low-voltage power distribution systems. Relying on the factory's 30 years of technical accumulation in high-voltage electrical manufacturing, it has been optimized for industrial and civil low-voltage power distribution scenarios. This 3.3 kv circuit breaker has the advantages of small size, light weight, convenient installation and simple maintenance, and is widely used in industrial plants, commercial buildings and infrastructure projects around the world.

This 3.3 kv circuit breaker adopts advanced vacuum arc extinguishing technology, with strong breaking capacity and fast arc extinguishing speed, which can quickly cut off normal load current and fault current to protect power equipment and personnel safety. The shell adopts a combined design of high-strength engineering plastic and metal material, with a protection grade of IP40 (indoor type) and IP65 (outdoor type), which can adapt to different installation environments. The product has a compact structure and can be directly installed in the switchgear or on the outdoor pole, greatly saving installation space. With a mechanical life of ≥20,000 times and an electrical life of ≥10,000 times, it operates stably and reliably with low maintenance costs.

 

Application Fields

 

The 3.3 kv circuit breaker is widely used in low-voltage power distribution systems in the industrial field, providing reliable power protection for production equipment in industries such as factories, mines, oil fields and chemical industries. In the commercial and civil fields, it is used in the power distribution rooms of office buildings, shopping centers and residential communities as low-voltage outgoing line switches and bus sectional switches. At the same time, the 3.3 kv circuit breaker is also suitable for power systems of important infrastructures such as railways, airports, ports and communications to provide power guarantee for the normal operation of these key facilities. In addition, it can also be used in the low-voltage side power distribution systems of new energy power stations such as wind power and photovoltaic power generation to ensure the stable transmission of new energy power.
