The Schneider Electric A9R81240 is an Acti9 iID residual current circuit breaker (RCCB), 2P, 40A, 30 mA sensitivity, Type AC.<\/p>\n
Replace a unit that no longer trips on test, or no longer latches, with the same rating (40A), sensitivity (30 mA) and type (Type AC).<\/p>\n

Follow local regulations; many installers test RCCBs every few months.<\/p>\n
230…240 V AC 50\/60 Hz per Schneider.<\/p>\n
No. An RCCB only detects earth leakage; use it together with circuit breakers. Schneider gives a rated conditional short-circuit current of 10 kA.<\/p>\n
30 mA, Type AC, per Schneider.<\/p>\n
