Overview

Every detail is designed carefully, focusing on quality, making products carefully and using them for a long time. Ac Current Relay is suitable for overload and open phase protection of AC 50Hz three-phase motor. The relay can protect the motor with a starting time of up to 90 seconds. The relay adopts LED nixie tube display, which has the obvious advantages of intuitive display, convenient use, small volume, simple installation and so on.

Our Ac Current Relay is applicable to production lines such as printing, packaging, plastics, food and metallurgy, and occasions requiring remote observation data and automatic control of production process. It is compact and easy to use and install. Reading is intuitive and clear without conversion. It is widely used and has won a good reputation.
