Product details

The Schneider Electric A9DF3732 is an Acti9 iCV40 residual-current circuit breaker with overcurrent protection (RCBO), rated 32 A with a C-curve and integrated 30 mA earth-leakage protection. It clips onto a DIN rail, occupies 10 modular pitches (90 mm width), and is rated for 6 kA breaking capacity at 400 V AC, 50/60 Hz, per EN/IEC 61009-2-1.

The 30 mA earth-leakage sensitivity provides personnel protection against direct contact, while the C-curve (5–10 x In) avoids nuisance tripping on loads like small motors or capacitor banks that draw a brief inrush. The 3P+N configuration with neutral on the left is standard for three-phase outgoing feeders in TN or TT systems. IP20 rated for the body, IP40 inside a modular enclosure — fine for dry indoor panels.
