A small, powerful 20 W heater. It is easily installed thanks to the mounting clips for DIN rails that are fitted on the back of the heaters.
Because the heater is dual isolated with a plastic casing, the side surfaces' temperature never exceeds 85 °C, so the heater can be mounted relatively close to other components in the same installation, and there is no risk for fire damage.
The dual isolation also means that the heater does not need to be earthed.
The heat source consists of a PTC element, which provides a long and reliable lifetime even if the heater is in constant operation.
