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 within an aluminum profile, a terminal block, and optional touch protection. These heaters offer high performance, lightweight construction, and a compact design.
The aluminum profile ensures efficient heat transfer using the chimney effect, enabling up to 240W of heating power without a fan. The DIN clip with thermal insulation allows easy and space-saving installation on DIN rails.
PTC convection heaters are commonly used in control cabinets to protect electronic components from moisture and frost.
Models over 100W come in five power levels (100W to 240W) and support voltages from 110 to 240V AC or DC. The 240W version includes two aluminum profiles for maximum power.
