The Schneider Electric A9DC6925 is a 3P + Ns Acti9 iC60 RCBO — a combined residual current breaker with overcurrent protection (RCBO) — rated 25 A at 30 °C with an integrated 30 mA earth-leakage sensitivity. Its 6 kA breaking capacity (Icn at 400/415 V) and C-curve thermal-magnetic trip make it a standard choice for final subcircuit protection in TN earthing systems on 50/60 Hz AC networks. The 6 kA Icn at 400/415 V means this RCBO safely interrupts a fault current up to 6 kA without welding its contacts or failing to clear — that is the standard domestic and light-commercial fault level under AS/NZS 61009.1, so it is sized for most distribution boards downstream of a higher-rated upstream device. The 30 mA earth-leakage sensitivity provides additional protection against electric shock for people and equipment, meeting typical socket-outlet and lighting circuit requirements in residential and commercial installations.
Clip-on mounting to standard DIN rail (35 mm). The device occupies 6 x 9 mm pitches (54 mm width) and fits a 45 mm grid distance. Dimensions: 112 mm height, 77.2 mm depth. Tightening torque 2.5 N·m for the power circuit. Neutral position is left; padlockable with a Ø 4 mm padlock for lockout/tagout.
Standards compliance: AS/NZS 61009.1 (Australian/New Zealand standard for RCBOs). Tropicalisation class 2, relative humidity 95% at 55 °C. Electrical durability 5000 cycles, mechanical durability 20000 cycles. Limitation class 3.
