Enclosure heater with fan

CSF 028

This PTC enclosure heater with fan and fixed thermostat provides condensation protection in the enclosure and casing. It is particularly space-saving. The integrated fixed thermostat is available in two temperature presets. The heating is touch-safe for the application thanks to the touch-safe plastic coating of the heater body.

PTC heating element: temperature-limiting, direct response behavior
Toch-safe heat protection, therefore safe to touch
Screw fixing and mounting with clip fixing for DIN rail 35 mm possible
Electrical connection via pressure clamps
Temperature safety cut-out to prevent overheating
