GRV8-03三相电压监控继电器缺相错相断相序保护器(GRV8-03/M460)

以下技术资料为英文原文。

Features

1. The monitoring relay can monitor its own working voltage, and has phase sequence protection and phase failure protection.

2. 8 kinds of rated voltages are adjustable, which can be applied to voltages in all regions of the world.

3. The working status of the relay is indicated by the LED indicator.

4. Ultra-small size, easy to install.

5. It is suitable for connection control of mobile equipment, preventing reverse operation of equipment, normal/emergency power switch, and preventing phase failure of electric loads, which may cause accidents.
