Product Overview
V25S150P is a 25 mm Littelfuse UltraMOV 25S high-energy MOV. The larger disc format provides substantially higher surge and energy capability than common 14 mm and 20 mm MOVs, with a 22 kA single-pulse 8/20 µs rating and 300 J energy specification.
The 150 V grade is rated for 150 VAC RMS or 200 VDC continuous operation and is intended for equipment that needs a robust radial surge suppressor rather than a compact board-level MLV.

High-Energy MOV Considerations
A high single-pulse rating does not mean unlimited repetitive surge life. Expected surge count, waveform, ambient temperature and protective coordination should be included when determining margin.
