500 Amp Three-Phase Current Meter

See heavy-duty savings.

Monnit’s ALTA Wireless 500 Amp Three-Phase Current Meter monitors for abnormal consumption, imbalances, or supply faults. Ideal for heavy-duty machinery or an entire building, this industrial-grade current meter monitors RMS current (min, max, and avg), duty cycle of each phase, and combined amp hours (all phases).

If one of the monitored metrics deviates from your preset thresholds, get an alert via text, email, or call. Current meter notifications can also be based on amperage/power levels.

Three reasons why your operations need a Three-Phase 500 Amp Current Meter

  • Prevent failure: Rising power consumption may indicate overdue maintenance or an imminent failure—sensors keep you ahead.
  • 15-minute install: Simply wrap the device’s CTs around the wires of your three-phase system—no direct wiring for safety’s sake.
  • Data-driven insight: Collect operation insights to extend machine life and plan maintenance—prevent downtime and save money.
