The Delta HG-140-100W heater uses a self-regulating PTC semiconductor thermistor and is intended exclusively for use in enclosed distribution cabinets. It helps prevent condensation and maintain the appropriate operating temperature for equipment. For optimal air circulation, install it vertically at the bottom of the cabinet.

To maintain a stable temperature, connect a suitable thermostat in series. Maintain a clearance of at least 50 mm from cables and other devices. PTC thermistors are not designed to be connected in series.
