Features

The three-display current and voltage meter protector highlights the core advantage of triple-screen simultaneous display of three-phase electrical parameters, which can accurately show three-phase current/voltage (or combined parameters such as current, voltage, power and electric quantity) in real time simultaneously. It integrates full-dimensional electrical protection functions including overvoltage, undervoltage, overcurrent, overload, phase loss and three-phase unbalance, and supports the customization of parameters like protection thresholds and action delays, with the function of automatic and manual fault reset. Adopting standard 35mm DIN rail mounting, it is suitable for three-phase power distribution scenarios such as AC380V. Featuring a flame-retardant structure for high safety and reliability, as well as easy installation and maintenance, it is widely used for power consumption monitoring and safety protection of key industrial three-phase equipment including motors, distribution cabinets and water pumps.
