Enclosure heaters are designed to prevent damage or malfunction of electric/electronic components in electrical cabinets and enclosures due to moisture infiltration. The heaters prevent condensation and freezing by providing some heat within the cabinet. Constructed of PTC ceramic element with ventilator, the heater is connected with open line ends or the optionally available connector block. The self-regulating, temperature-limiting device has a black plastic housing (UL 94V-0) and can be mounted vertically with the air outlet on top.
