Rated current is 1.6 A at 35 °C, derated to 1.52 A at 40 °C, 1.48 A at 45 °C, 1.44 A at 50 °C, 1.4 A at 55 °C, and 1.36 A at 60 °C.
Halogen-free and silicon-free construction reduces corrosive outgassing in confined enclosures — relevant for sealed railway junction boxes. Operating temperature range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, matching the mechanical environment of traction equipment.
