    Touch-Safe Small Heater Type CS/CSF (Semi-Conductor) with PTC-Resistor

    Key Features

    • Small size
    • Ensure a minimum operating temperature
    • Prevent condensation
    • Advantages of heaters with PTC-resistor: Dynamic heating up, temperature limiting, wide voltage range

    Product Description

    Cabinet heaters are used for heating up the air inside a control cabinet. häwa offers a wide range of cabinet heaters from 10 to 1200 W to optimize the functionality of electric and electronic components, to ensure a minimum operating temperature and for frost monitoring in case of low ambient temperatures and high humidity.

    The design of the heater supports the natural convection which results in a high air-flow of warm air

    The surface temperatures on the accessible side surfaces of the housing are kept down as a result of the heater design

    Heating element: Resistor (PTC) temperature limiting

    The heaters are designed for permanent operation

    Quick mounting: snap-on attachment to 35 mm DIN rail
