Three-phase monitoring relay NA10
The NA10 is an electronic device designed to check the correct sequence and phase loss in a three-phase network.
- Sequence and phase failure control in a three-phase network
- 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
