The Megger PSI410 Phase Sequence Indicator is a robust tool for electricians working on three-phase motor, pump, and air conditioning systems, rapidly identifying phase sequence (195-265 V, 50 Hz ±1%, up to 500 V) to prevent damage from incorrect phasing.
It features a triple bi-colored LED display (green for clockwise rotation, red for counter-clockwise) with a slow rotation speed for clarity, accompanied by audible tones (continuous for clockwise, warble for counter-clockwise). Phase presence is indicated by green LEDs (present) or red LEDs (missing). Self-powered from the supply, it requires no batteries and supports dual phase color coding (Brown/Black/Grey, Red/Yellow/Blue).
The 850 g, CAT IV 600 V device, with a rugged case (78 x 137 x 31 mm), operates in 5 °C to 40 °C and includes 830 mm fused test leads (10 A 600 V) with crocodile clips and prods (<4 mm tip). Compliant with IEC61010, it’s suited for intermittent testing. The kit includes the PSI410, crocodile clips, prods, and a one-year warranty, ideal for quick phase sequence checks in industrial settings.
