Fluke PRM-5-EUR Indicador de sequência de fases, 40-600 V AC, 15-400 Hz, CAT III 600 V 4375961

Operating from 40 V to 600 V AC across 15 Hz to 400 Hz, this phase rotation indicator verifies clockwise or counter-clockwise rotation on three-phase systems without batteries—it draws power directly from the circuit under test.

Overview

The Fluke PRM-5-EUR is a compact phase rotation indicator built for electricians and maintenance technicians. It determines phase rotation direction and confirms phase presence using LED indicators. The unit is powered by the measured circuit, eliminating battery concerns. Integrated test leads with alligator clips allow direct connection to live conductors.
