PTC Heater / SL

PTC Heaters / SL includes four types of Cabinet Heaters with capacities: 250, 350, 500 and 650W at 20 ° C. They are designed to fit in the same compact housing. This facilitates cabinet design and makes it easy to expand capacity. The robust, high-temperature resistant housing measures only 86 mm x 100 mm x 105 mm. Our PTC Heaters are equipped with two individual heating circuits and a strong heating fan to ensure the optimum temperature in the electrical cabinet. and to also minimize moisture formation.

All models are calibrated for optimal performance at 20°C, ensuring consistent and reliable heating under varying conditions. The element has an integrated temperature guard that shuts off in the event of fan failure and to prevent overheating.
