M3U/H3U series three-phase voltage control relays

H3US and M3US relays control three-phase networks: Overvoltage between phases and undervoltage between phases.
The H3USN relay controls three-phase networks: Overvoltage between phases and neutral, undervoltage between phases and neutral, and the absence of neutral.
Multi-voltage products.
Controls its own voltage supply.
Measurement in true RMS.
LED status display.
