Three-phase monitoring relay NA10

Functionl description

The NA10 is an electronic device designed to check the correct sequence and phase loss in a three-phase network.

Application fields

  • Sequence and phase failure control in a three-phase network

Main features

  • Three-phase supply voltage: 200VAC ÷ 500VAC (50 ÷ 60 Hz)
  • Exchange relay output:  250V, 3A
  • 2 Signaling LEDs: yellow for main power supply presence, green to indicate the correct sequence of phases
