Type A catches pulsating DC faults from electronics or rectified loads, not just pure sine-wave AC. Snaps onto DIN rail (REG profile), mounting position any — no orientation restrictions. Supply can enter top or bottom. Rated IP20 once installed with conductors connected — it's an enclosed-panel device, not for wet environments. ## Thermal derating — the number that matters The 40 A rating holds only at 40 °C ambient. Above that, the continuous current drops fast: 38.1 A at 45 °C, 35.59 A at 50 °C, 32.29 A at 55 °C, 28.19 A at 60 °C, 23.3 A at 65 °C, 17.62 A at 70 °C. Factor that into the load schedule.
