Natural Convection Heating Component

Nimbus NG series PTC convection heaters are powerful air heaters designed for various electrical enclosures. They feature a PTC heating element housed in an aluminum profile, with a terminal block and optional touch protection. These heaters combine high performance, lightweight, and a compact design.
The aluminum profile maximizes heat transfer using the chimney effect, delivering up to 75W of heating power without a fan. A DIN clip with thermal insulation allows for easy, space-saving installation on DIN rails.
PTC convection heaters are commonly used in control cabinets to protect electronic components from moisture and frost.
Models under 100W are available in four power options from 20W to 75W. The short aluminum profile supports voltages from 110 to 240V AC or DC (multi-voltage capable).
