The 0.5 A rating at 45 °C derates to 0.48 A at 50 °C and 0.47 A at 55 °C — factor that into your panel ambient if the MCB shares a crowded enclosure. For UL 1077 / CSA C22.2 No.235 applications, the interrupting rating is 5 kA — a critical number if the panel carries a North American listing requirement.
Touch protection is integral, and the housing is sealable for panel-side lockout/tagout procedures.
Environmental tolerance
Operating ambient range is -40 °C to 75 °C, with humidity derating: max 95% RH up to 55 °C, tapering to 55% at 70 °C and 35% at 75 °C. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — sufficient for general industrial machinery but not heavy rotating equipment without additional support.
