Rated 40 A at 30 °C with a Type C tripping characteristic, it interrupts faults up to 6 kA per EN 60898 and IEC 60947-2. The instantaneous design means no intentional time delay on the residual-current side — it trips on fault without waiting, which matters for equipment protection in circuits where nuisance tripping from transient leakage isn't a concern.
Thermal derating and ambient range
At 40 °C it derates to 36.4 A, at 45 °C to 34.8 A, at 50 °C to 33.2 A, and at 55 °C to 31.2 A. That's a roughly 22% drop from 30 °C to 55 °C — plan your continuous load headroom if the panel sits near hot equipment. The part is rated for -40 °C to 75 °C storage and operating ambient, which covers mill-floor conditions near furnace zones or outdoor cabinets in cold climates.
Mounts in any position (vertical, horizontal, upside-down — no restriction) and accepts supply from top or bottom. The 77 mm depth and 72 mm width fit standard DIN-rail enclosures; installation depth is 70 mm. Halogen-free and silicon-free construction suits clean-room or corrosive-area installations where outgassing matters.
