1.Protect the electrical equipment when there is an over-voltage/under-voltage (set the voltage protection) in the line, it also has the overload and short-circuit protection function. 2.High breaking ability, fast tripping, can achieve remote control, product modular guide rail installation. 3.Maintenance can be remote lock, remote unlock, with mechanical locking. 4.Pressure loss protection: when the under-voltage function is opened, with pressure loss protection, that is, the power off trip, at this time, the product cannot be manually closed. 5.voltage, current, leakage current, temperature action value can be set. Real-time voltage, current, leakage current, temperature and power value can be read, with metering function. The manual or automatic mode can be set.
