Distribution box withstand temperature
The ideal temperature for an electrical enclosure recommended by Pfannenberg is approximately 35°C. This not only protects the components but also minimizes the risk of condensation and cuts energy costs. The IEC 61439-1 sets the thermal limit in busbars working at the maximum working load. Here, 140°C (which is 105K over the ambient temperature of 35°C) is the upper safe temperature limit. The methodology follows two distinct stages: Using strategically placed external sensors, technicians capture thermal patterns across the cabinet's exterior. Temperature Resistance of the Flame-Retardant Casing: The PA66 nylon material has excellent thermal stability. Our distribution boxes are made of thickened stainless steel with good high-temperature resistance, which can withstand the long-term high-temperature environment of 80℃-120℃ in workshops, and the sealed design prevents dust and oil pollution from damaging internal electrical components.
