Double-clamp phase voltmeter for electricians

The ETCR 4020 is a digital phase voltmeter built for electricians who need simultaneous two-channel readings on site. Its large-calibre clamps accept conductors up to 35mm x 40mm, letting you measure current and voltage without breaking the circuit. The instrument targets maintenance crews and commissioning engineers working on three-phase systems.

Measurement ranges and phase limits

AC current is measured from 0 mA to 600 A on each channel, while AC voltage covers 0.00 V to 600 V. Phase angle between voltage–current, current–current or voltage–voltage spans 0.0° to 360.0°. The meter also derives frequency, phase sequence, active, reactive and apparent power plus power factor, but it cannot measure DC quantities or voltages above the stated 600 V limit.

Red housing with 35 by 40 mm jaws

The red enclosure houses jaws sized 35 mm by 40 mm, so thick busbars or bundled cables fit without adapters. A three-year parts and one-year labour guarantee backs the build, though the standard box ships without batteries due to air-freight rules. No English manual is included in the package; documentation must be requested separately after purchase.

Questions about this item

Should I choose the 35mm x 40mm clamp size for my cables?

The CT opening measures 35mm by 40mm, so it fits conductors up to those dimensions; verify your cable diameter before ordering.

What does the 600A current range mean when I clamp onto a live conductor?

It measures AC current from 0mA to 600A on each channel simultaneously, displaying the true RMS value on the meter.

How does the 600V voltage limit affect phase-angle readings?

Phase angle between voltage and current is shown from 0.0° to 360.0° while the line voltage stays below 600V.
