The 30 mA sensitivity provides personal protection against direct contact, while the Type A-SI classification means it handles pulsed DC fault currents and is super-immunised against nuisance tripping from high-frequency harmonics or transient surges — critical for circuits with variable-speed drives, UPS systems, or LED lighting where standard Type A RCCBs can false-trip. With an impulse withstand of 3 kA (8/20 µs waveform) per IEC/EN 61008-1 and IEC/EN 61008-2-1, this RCCB tolerates surge events common in industrial mains without unnecessary disconnection. The 4-pole device occupies 8 x 9 mm pitches (72 mm width), with an 18 mm phase-to-phase connection pitch. Height is 86 mm, depth 76 mm. Tunnel-type terminals accept up to 50 mm² rigid or 35 mm² flexible cable; tightening torque is 3 N·m. IP20 rated for the device body, IP40 for the modular enclosure per IEC/EN 60529. Suitable for installation in enclosed distribution panels where incidental contact protection is sufficient. Ambient storage range is -40 to 85 °C.","metaTitle":"Schneider A9R31492 Acti9 RCCB-ID, 4P 125A 30mA Type A-SI","metaDescription":"Schneider Electric A9R31492 Acti9 RCCB-ID residual current circuit breaker. 4 poles, 125 A rated current, 30 mA sensitivity, Type A-SI (Super Immunised). 400 V AC, 50 Hz.

The A9R31492 is a 4-pole 125 A Type A-SI unit. For lower current requirements, the same family offers 2-pole and 4-pole variants at 25 A, 40 A, 63 A, and 100 A. All share the same 30 mA sensitivity and Type A-SI characteristic, so the choice is driven by the load current and the number of phases needing protection."},{"question":"What compliance documentation does Schneider provide for A9R31492?","answer":"The A9R31492 carries a VDE quality label and is certified to IEC/EN 61008-1 and IEC/EN 61008-2-1.
