Three-phase digital phase volt-ampere meter

The ETCR 4300 measures three AC currents up to 20.0A and three AC voltages up to 600V simultaneously. It also reads phase angles from 0.0° to 360.0°, frequency, phase sequence, active power, reactive power, apparent power and power factor. Electricians and maintenance engineers use it for transformer wiring group checks and differential protection testing without opening the circuit.

Clamp aperture limits conductor size

The current transformer accepts conductors up to F8mm in diameter. This single physical constraint decides whether the meter fits the cables on site. If the conductors are larger, the jaws cannot close and the measurement cannot be taken.

Battery-powered handheld operation

The instrument runs on internal batteries during normal use, so it adds no load to the panel under test. No external power supply or cooling is required, and the red handheld housing is rated for line voltages below 600V.

Questions about this item

What does the 600V maximum voltage range mean for everyday three-phase work?

The meter reads up to 600 V AC line voltage, covering standard low-voltage three-phase supplies without needing external potential transformers.

How does the 8 mm CT jaw size limit the conductors I can clamp?

The F8 mm current transformer opening fits cables or bus-bars up to about 8 mm diameter; larger conductors require a different clamp.

What clearance does the red hand-held unit need inside a panel?

The compact clamp body and leads are designed for typical panel space; allow room for the 8 mm jaw to close fully around each phase conductor.
