Three Phase Voltage, Current and Frequency Digital Meter (LL / LN) — 1 Pcs (Meter with 100A CT) Overview This threephase digital meter provides clear, realtime monitoring of voltage (both linetoline and linetoneutral), current (via the included 100A current transformer), and frequency. It is a singlepackage solution (1 piece) that simplifies electrical monitoring and helps protect equipment, improve system visibility, and support better decisionmaking in commercial and industrial installations. Key benefits Complete threephase monitoring in one device: measures voltage (LL and LN), current, and frequency so you can assess power quality and load conditions quickly. Includes a 100A CT: current measurement is ready out of the box without separate transducers. Faster troubleshooting and preventive maintenance: use the meter to detect imbalances, abnormal voltages, or frequency deviations before they cause downtime. Clear digital readings: numeric output makes it easy for technicians and facility managers to read and record values. Main features and attributes Functionality: Digital measurement of threephase voltage (LL and LN), current (via CT), and frequency. Realtime numeric display for quick assessment. Compatibility: Designed for threephase electrical systems; supports both linetoline and linetoneutral voltage measurement methods. Includes one 100A current transformer for current sensing up to 100 A through the CT. Package: Supplied as one complete meter unit with a 100A CT (1 Pcs). Installation: Intended for panel mounting and direct integration into electrical distribution panels and control systems. Wiring connections for voltage inputs and CT secondary are provided on the meter. Durability and performance: Built for continuous electrical system monitoring to support routine checks and longterm trend observation. Typical applications Electrical distribution panels and switchboards: Monitor phase voltages, current draw and frequency across threephase circuits to spot imbalances and overloaded phases. Generators and backup power systems: Verify generator output voltage and frequency under load and ensure stable operation during transfer events. Industrial and commercial facilities: Use for motor control centers, HVAC systems, manufacturing equipment and building power monitoring to maintain energy efficiency and prevent unexpected trips. Who should use this meter Electricians and panel builders who need a compact, singledevice solution for threephase monitoring. Maintenance and facility managers who require straightforward, reliable readings of voltage, current and frequency. System integrators and OEMs looking for a meter with a builtin 100A CT for quick deployment. What's included One threephase digital voltage, current and frequency meter One 100A current transformer (CT) Practical notes The meter measures linetoline and linetoneutral voltages; choose the appropriate measurement configuration for your system wiring. The included 100A CT is used for current measurement; confirm CT orientation and secondary wiring when installing to ensure accurate readings. For safe and correct installation, follow standard electrical procedures and local regulations. If unsure, consult a qualified electrician. This product delivers a straightforward, integrated solution for threephase monitoring where voltage, current and frequency information is needed in a single meter with an included 100A CT.
