Megger PSI410 Phase Sequence Indicator (1001‑612)
The Megger PSI410 is a compact, self-powered phase sequence indicator for three-phase systems (up to 500 V). Its tri-color LEDs and audible tones quickly identify phase sequence (clockwise for correct, warbling for reverse) and missing phases. No batteries are needed—the unit draws power from the connected phases. Designed for industrial use, it features IP54 protection and CAT IV 600 V safety certification
