Line Voltage & Phase Sequence Detector

208A-480VAC

The Model 208 Line Voltage & Phase Sequence Detector offers essential utility for industrial electrical systems. Operating at 480V and 50/60Hz, this device provides continuous monitoring of line conditions. It accurately indicates a normal operating state, identifies any missing phases, and determines the correct phase sequence as either ABC or CBA. Its fly leads facilitate straightforward integration. The detector's robust ABS plastic enclosure ensures durability in various environments. This tool assists technicians in maintaining system integrity by providing clear visual feedback on critical power parameters. By clearly showing conditions like "Phase A Missing" or "CBA Rotation" via specific lamp combinations, it supports operational continuity and helps prevent potential equipment damage due to incorrect phase rotation or loss. Its compact dimensions (2.00 x 2.94 x 4.55 inches) and light weight (3.2 oz) allow for versatile placement.

FAQs

What voltage and frequency does the 208A-480V detector monitor?
The 208A-480V detector monitors 480V systems at a frequency of 50/60Hz.
How does the detector indicate a missing phase?
If Phase A is missing, lamps ABC, CBA, B, and C will be lit. For Phase B missing, lamps ABC, CBA, A, and C illuminate. If Phase C is missing, lamps ABC, CBA, A, and B are lit.
What material is used for the enclosure of the Model 208 detector?
The enclosure of the Model 208 detector is constructed from ABS plastic.
