Three-phase clamp meter for 25–100 Hz systems

The ETCR 7300 measures AC current up to 1200 A, three-phase voltage up to 600 V and phase angles from 0.0° to 360°. It captures active, reactive and apparent power, power factor, frequency, phase sequence and energy. Non-contact clamping suits electricians working on distribution panels, motor feeds and grounding conductors.

Check cable size and voltage before ordering

The CT aperture is 80 mm by 80 mm, so it fits round cables up to 80 mm diameter and flat grounding strap. Line voltage must stay below 600 V and the measured frequency must fall between 25 Hz and 100 Hz. Verify that your system uses three-phase AC within these limits and that the jaw can close fully around the conductor.

Passive clamp design keeps thermals and noise low

No internal fan or active cooling is present; the instrument draws minimal power from its own supply during measurement. The magnetic-shielded core resists external interference without generating noticeable heat. Operation is silent, making it suitable for extended logging sessions in switchrooms or substations where audible noise must be avoided.
