20 Amp Three Phase Current Meter

Expert measurement & savings

Not measuring power and machine operation? You’re likely missing energy savings.

As drop-in energy data specialist, Monnit’s 20 Amp Wireless Current Meter installs within 15 minutes to monitor a facility’s three-phase power system or monitor machine power draw and collect usage stats. Insights help prevent failure, economize machine operation, extend machine life, and lower overhead.

Prevention & Planning: How a Current Meter Helps

The sensor uses three 0–20 amp current transducers to monitor RMS current (min, max, and avg), duty cycle of each phase, and combined amp hours (all phases). Data is collected for analysis and sharing—ideal for multi-machine facilities or firms with decentralized operations.

Additional value-added benefits

  • Instant sensor alerts (text, email, or call) if a monitored variable exceeds your thresholds.
  • Identify excessive machine operation to prevent unnecessary burnout.
  • Know when a machine starts using more power—often a sign that maintenance is needed.
  • Be aware of external supply issues to minimize disruptions.

Protect machines, productivity, and profits by incorporating Monnit’s Wireless 20 Amp Three-Phase Current Meter today.
