It protects against sinusoidal AC fault currents in final circuits — the 300 mA threshold suits sub-distribution or feeder protection where a higher trip level avoids nuisance tripping from leakage in long cable runs or equipment with normal leakage. Rated operational voltage is 380...415 V AC at 50/60 Hz, with a rated insulation voltage of 500 V AC. Breaking capacity is 1500 A (Idm and Im), adequate for downstream fault clearing in a coordinated panel. Wire stripping length is 14 mm for top or bottom connection. Neutral is on the left, consistent with the Acti9 modular range layout. ## Protection class and environmental limits Type AC detection means it responds only to sinusoidal alternating residual currents — not pulsed DC or smooth DC. The trip is instantaneous (no time delay), so it clears earth faults immediately. The residual current tripping technology is voltage independent — it operates without an auxiliary supply, relying on the fault current itself to energize the trip mechanism. IP20 rated (finger-safe terminals) per IEC 60529; IP40 when housed in a modular enclosure. Electrical durability is 15,000 cycles under AC-1 (resistive load), mechanical durability 20,000 cycles. The device is designed for outgoer positions in distribution boards.","metaTitle":"Schneider Electric A9R14440 Acti9 iID RCCB, 40A 300mA Type A","metaDescription":"Schneider Electric A9R14440 Acti9 iID 4P RCCB, 40A rated current, 300mA Type AC earth-leakage protection, 380-415V AC.
