The Schneider Electric A9R75440 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 iID K series, rated at 40 A with 300 mA earth-leakage sensitivity. The part clips onto a DIN rail (mounting support: DIN rail, clip-on) and fits an 8-module width (72 mm). Current-production status is confirmed.
The 300 mA sensitivity suits fire-protection or general-purpose earth-leakage protection where personnel shock protection is not required.
The neutral position is on the left.
It belongs to the Acti9 range, specifically the iID K series of residual current circuit breakers.
