FZB10-NM3 is an automatically switched multi-function voltage-compensated relay with protector designed by China Electric Apparatus Research Institute. This type of device is widely applied in relay protection and automation products and the circuit breaker of relay protection device and power metering device. It is packaged with a steel enclosure, and the whole model is divided into three functions which includes the observation part, the list part and a metering part.

The FZB10-NM3 is equipped with a set of sensitive current transformer which can measure the connection of current and the short circuit current. It also has a number of relays and controllers that are used to handle unexpected situations, such as over-current protection and short circuit protection. At the same time, it is able to monitor the voltages and provide accurate and timely voltage and current information for the necessary control.

The working principle of the FZB10-NM3 is simple and easy to use. It is basically a voltage-compensated relay device. It uses the principle of impedance matching to detect both the current and the voltage of the power line. When the voltage or current is too high or too low, the relay will automatically switch off the power line. It is also equipped with a manual reset switch, which can help to manually reset the relay if it is not working properly.

Apart from its use in relay protection and automation, the FZB10-NM3 is also widely applied in many other fields, such as industrial motors and control systems. Its reliable and accurate operation helps to protect the human and environment in many aspects. It is an indispensable part of the circuit breaker and switchgear systems.

In conclusion, the FZB10-NM3 is a multi-function voltage-compensated relay with protector. Its working principle is based on impedance matching and it can provide reliable and accurate relay protection and automation. It is widely applied in many industrial areas, including the field of industrial motors and control systems. Thanks to its versatile applications, it is indeed an important addition to circuit breaker systems.
