GFR2D10030 is a three-phase AC relay with an overcurrent protection function. It is mainly used to trip breakers, so as to ensure the normal operation of the electricity network and avoid unnecessary damage due to short circuit and overload. It can be widely used in industrial and mining enterprises, power plants, commercial buildings, schools, hospitals, shopping malls and other places.

Working principle

The working principle of GFR2D10030 is based on the principle of electrical quantity control. When the load current of the circuit exceeds the set value, the relay will trip the breaker, thereby preventing overload and short circuit protection.

GFR2D10030 has three operation modes: overcurrent protection, overvoltage protection and undervoltage protection. The overcurrent protection mode has both fixed current and adjustable current protection. The adjustable current protection includes two operating levels: instantaneous overcurrent protection and time-delay overcurrent protection. The overvoltage and undervoltage protection mode can prevent the circuit from being damaged by overvoltage or undervoltage.

Application field

GFR2D10030 is widely used in the distribution of electricity, industrial automation control system and motor protection system. In particular, it has very good performance in synchronous motor protection system, long-distance power transmission and distribution system. In addition, GFR2D10030 can be used in low-voltage switchgear, residential power distribution system, smart grid system, industrial and mineral enterprises, power plants, commercial buildings, schools, hospitals, shopping malls and other places.

Its overcurrent protection function can effectively prevent short circuit and overload accidents. In addition, its overvoltage and undervoltage protection function can prevent any damage caused by overvoltage or undervoltage. Thanks to the reliable performance and multiple protection functions of GFR2D10030, it is widely used in distribution and transmission systems.

GFR2D10030 is an advanced AC relay with versatile functions. It is small in size, easy to install and operate, reliable in performance and equipped with multiple protection functions. It is a good choice for overcurrent protection and protection against overvoltage and undervoltage in electrical networks.
