GGD series AC LV fixed type switchgear

Description ：

The GGD AC low-voltage fixed switchgear is suitable for various scenarios with an AC rated frequency of 50Hz, a rated operating voltage of 380V, and a rated current of up to 3150A or below, including power stations, substations, factories, mines and other enterprises.

This product has a series of remarkable advantages. Its high breaking capacity can quickly cut off the current when a circuit failure occurs, effectively preventing the expansion of the fault range and ensuring the safe and stable operation of the power system. The excellent dynamic and thermal stability enables it to maintain reliable performance when facing the impact of short-circuit current, ensuring the safety of the equipment itself and the connected systems.

In terms of quality and standards, the GGD AC low-voltage fixed switchgear strictly complies with international and domestic authoritative standards. It fully meets relevant standards such as IEC439 "Low-voltage switchgear and controlgear assemblies" and GB7251.1 "Low-voltage switchgear and controlgear assemblies".

Q:What is a low-voltage switchgear?

A:Low - voltage switchgear is an electrical assembly for systems under 1000V AC or 1500V DC. It contains circuit breakers, switches, fuses, and contactors. These components control and protect electrical circuits. In industrial, commercial, and residential settings, it enables safe power distribution, interrupting current during faults to safeguard equipment and people.

Q: What AC voltage is low-voltage?

A: In the context of electrical systems, AC voltage is generally considered low - voltage if it is below 1000V. This includes common voltages like 110V and 220V used in residential and commercial applications. Low - voltage systems are designed to be relatively safer and are used for a wide range of electrical devices and power distribution at the user end.

Q: What is the IEC standard for low-voltage switchgear?

A：The main IEC standards for low-voltage switchgear are IEC 60947 and IEC 61439. IEC 60947 focuses on principles like safety and reliability for low-voltage switchgear and controlgear. IEC 61439 deals with switchgear and controlgear assemblies, covering verification methods, short-circuit tests and more. Besides, IEC TS 63058 and IEC TS 63290 are also related technical specifications.
