The Schneider Electric A9D73606 is an Acti9 ISPN Vigi residual current breaker with overcurrent protection (RCBO), combining a 1P+N thermal-magnetic MCB and a 30 mA earth-leakage module in a single 18 mm wide DIN-rail unit. Rated 6 A at 30 °C with a C-curve (magnetic trip 5 to 10 x In), it delivers 6 kA Icn breaking capacity at 230/240 V AC, 50 Hz. The integrated earth-leakage protection at 30 mA sensitivity makes it suitable for circuits requiring both overcurrent and shock protection in a single device.
The 6 A rated current (In) at 30 °C sets the continuous load limit for the protected circuit — sized for lighting or small socket outlets, not motor or high-inrush loads. The 6 kA Icn at 230/240 V AC is the short-circuit breaking capacity per IEC 61009-2-2; for installations with higher prospective fault current, this unit requires upstream overcurrent protection to limit let-through below 6 kA. The 30 mA earth-leakage sensitivity provides personal protection against direct contact (30 mA is the standard threshold for shock protection in residential and commercial final circuits).
The RCBO is certified to IEC 61009-2-2 and AS/NZS 61009.1, covering the combined overcurrent and residual-current requirements for Australia, New Zealand, and international markets. The unit is suitable for isolation (full disconnection on all poles) and includes an ON/OFF contact position indicator and locking facilities for lockout/tagout procedures.
