Industrial fan heater CSL 028

Short description
The CSL 028 enclosure fan heater prevents condensation and ensures even temperature distribution inside control cabinets. Push-in connectors and integrated clip or screw mounting simplify wiring and installation. The PTC heating element provides self-limiting temperature behavior. The touch-safe design increases operator safety.

Features

• Push-in connectors for fast wiring
• 2-pole or 4-pole connection options for separate control of heater and fan
• Clip or screw fixation integrated in a single casing
• PTC heating element with temperature-limiting behavior
• Touch-safe thermal protection to reduce risk for users
