Relais de protection de séquence de phases

Relais de protection de séquence de phases

Control for connection of moving equipment (like site equipment, agricultural equipment, refrigerated trucks). Control for protection of people and equipment against reverse running. Normal/emergency power supply switching. Protection against phase failure of driving load. Control its own supply voltage (true RMS measurement). Set 8 kinds rated operating voltage through knob.
