MONNIT Wireless 500 Amp Three-Phase AC Current Meter
MONNIT Wireless 500 Amp Three-Phase AC Current Meter is a wireless 500 Amp three-phase current meter designed to monitor electrical current across three phases in commercial and industrial systems. Using three current transformers, it can monitor RMS current, duty cycle and combined amp hours to help identify abnormal consumption, load imbalance and potential power faults. Operating on ALTA 433 MHz wireless communication, it is suited to machinery, HVAC equipment, motors and other high-current three-phase installations.
The MONNIT Wireless 500 Amp Three-Phase AC Current Meter is a wireless current monitoring sensor designed for three-phase electrical systems with currents of up to 500 Amps. It uses three current transformers connected through detachable leads to monitor each phase.
The meter is suited to commercial buildings, industrial equipment and heavy-duty electrical systems where changes in current consumption may help indicate operating issues, load imbalances or power faults. Monnit identifies applications including HVAC systems, industrial machinery, welding equipment, air compressors and conveyor system motors.
How it works
- Three current transformers are positioned around the conductors being monitored.
- Each current transformer connects to the sensor through its corresponding detachable lead and connector.
- The sensor monitors RMS current, including minimum, maximum and average values, along with the duty cycle of each phase and combined amp hours.
- Collected data can be used with Monnit's monitoring system to identify changes against configured thresholds and generate notifications.
Why choose this product
- Designed specifically for high-current, three-phase electrical monitoring.
- Provides visibility across all three monitored phases rather than a single current measurement.
- Supports monitoring for abnormal power consumption, load imbalance and supply faults.
- Uses wireless communication to transmit monitoring data from the installation point.
- The exact model is the 433 MHz industrial version, identified by part number MNS2-4-IN-3P-500D.
Benefits
- Helps maintenance teams observe changes in electrical current over time.
- Can support earlier identification of unusual equipment behaviour.
- Provides useful operating data for maintenance planning and equipment analysis.
- Suitable for monitoring larger commercial and industrial electrical loads.
