The 35 A rating holds at 30 °C and 40 °C, then derates: 34 A at 45 °C, 32.9 A at 50 °C, 31.8 A at 55 °C, and 30.8 A at 60 °C (–). The 18 mm width takes one modular unit on a standard DIN rail, so it fits tight layouts.
This MCB is designed for mechanical engineering and industrial applications. It's a standard branch-circuit protector for control transformers, solenoid valves, and small motor loads in panels where the C-curve prevents nuisance tripping on inrush. The IP20 rating is fine inside a closed panel; the handle area is IP40.
