Function: 1. 2.5mm2 wire with 2‑3 pole tip, 1 is the fire line input line, 2 is the neutral line output line, supports 12‑250V wide voltage input. 2. Rear rail hole for easy mounting on 35mm rails. 3. The PC material housing has high-quality heat resistance, high impact resistance and other physical and mechanical properties. 4. Excellent electrical insulation, elongation, dimensional stability and chemical resistance. High durability. 5. The task of the mechanical humidity controller MFR012 is to control the electric heating in such a way that the dew point at a key moment raises the relative humidity by over 65%. In this way, condensation and corrosion are effectively prevented.
