The Type A-SI (Super Immunised) classification means it handles pulsed DC fault currents from electronics (VFDs, switched-mode supplies) without nuisance tripping — a common pain point in modern industrial panels. The 30 mA sensitivity is the standard for personnel protection (direct-contact shock prevention) per IEC 60364. The 40 A rated current matches a 3-phase outgoing feeder for a sub-distribution board or a large machine supply. Breaking capacity is rated at Idm 1500 A and Im 1500 A — adequate for most final circuits where the upstream MCB or fuse already limits fault current below that level. Type A-SI (Super Immunised) adds immunity to high-frequency leakage currents and transient surges that would trip a standard Type A RCCB. The voltage-independent tripping mechanism means the device detects leakage even if the phase voltage collapses — it does not rely on an electronic circuit for the trip decision. This is a key reliability feature for safety-critical circuits. The 8/20 µs impulse withstand of 3000 A confirms it survives lightning-induced or switching surges on the line side without internal damage. Clip-on DIN rail mounting, neutral on the left side. Terminals accept up to 35 mm² rigid or 25 mm² flexible wire; strip length 14 mm, tighten to 3.5 N·m. The 72 mm width (8 x 9 mm pitches) fits standard modular enclosure spacing.","metaTitle":"A9R31440 Acti9 iID RCCB, 4P 40A 30mA Type A-SI, 380-415V","metaDescription":"A9R31440 Schneider Acti9 iID 4P RCCB, rated 40 A with 30 mA earth-leakage sensitivity, Type A-SI (Super Immunised).
