Megger PSI410 Phase Sequence Indicator

Overview

The Megger PSI410 is a rugged, professional phase sequence indicator used to confirm the phase rotation of three-phase supplies before connecting motors, drives and other rotation-sensitive equipment. It gives both a visual indication, through three red/green LEDs, and an audible tone – a continuous tone for correct (clockwise) rotation and a warbling tone for reverse (counter-clockwise) – so the result is clear even in noisy or awkward locations.

Powered directly from two of the phases under test, the PSI410 needs no batteries and connects in any position. With a CAT IV 600 V safety rating, IP54 protection and colour-coded leads, it is well suited to electricians and commissioning engineers who need a fast, dependable check of phase sequence on installations up to 500 V phase-to-phase.
