Leakage Current and Heat

Why ventilation and Uc selection matter in hot climates.

Hot climate SPD installation

Ambient temperature

Middle East and tropical plant rooms can run very hot. High ambient plus leakage increases thermal stress.

Enclosure design

Do not bury SPDs in unventilated pockets next to heat sources. Follow manufacturer ambient limits.

Grid swell

Sites with frequent voltage swell need careful Uc selection to avoid accelerated aging.
