Three-phase power tester for industrial electricians

The ETCR 7300A measures AC current and leakage current from 0.0A to 2000A, three-phase AC voltage up to 600V, and phase angles between voltages and currents across 0.0° to 360°. It also captures active, reactive and apparent power, power factor, total power, frequency, phase sequence and electrical energy. Data storage holds 200 groups for later review.

Clamp interface limited to 80mm conductors

The built-in CT aperture measures 80mm by 80mm, so only cables or flat steel grounding wires that fit within that window can be tested without contact. Line voltage must remain below 600V and the frequency range is 25Hz to 100Hz. Measurements outside those electrical limits or on conductors larger than the clamp opening are not supported.

Handles full three-phase panels up to 2000A per

The tester comfortably covers typical industrial feeders and motor circuits rated up to 2000A, storing 200 reading sets for energy audits or troubleshooting. It runs out of headroom on services exceeding 2000A, on voltages above 600V, or on frequencies outside the 25Hz to 100Hz band. The 80mm clamp also prevents use on oversized busbars or bundled cables that exceed the aperture.

Questions about this item

How do I choose between the current and voltage ranges on the ETCR 7300A?

The clamp measures AC current from 0.0A to 2000A and three-phase AC voltage from 0.00V to 600V, so select the range that covers the expected load on the circuit under test.

What does the 2000A current rating mean when I clamp the meter on a live conductor?

It indicates the maximum AC current the 80mm jaws can measure without contact; readings above 2000A will exceed the specified range.

What interface does the tester use and what does it limit in practice?

The 80mm x 80mm current transformer clamps around conductors up to 80mm diameter, setting the physical limit for cable or busbar size that can be measured.
