The Schneider Electric A9Z22291 is an Acti9 iID RCCB — a 2-pole, 100 A device with 100 mA earth-leakage sensitivity, Type A protection, rated for 220-240 V AC 50/60 Hz.
Rated at 100 A continuous, this RCCB handles the full load of a main distribution board or a high-current sub-feed. The 100 mA sensitivity provides earth-fault protection while tolerating normal leakage from equipment like UPS systems or VFDs. The rated conditional short-circuit current is 10 kA. Breaking capacity is listed as Idm 1500 A and Im 1500 A — the RCCB's own making/breaking capacity for residual and overcurrent faults. The instantaneous trip (no intentional delay) means it clears earth faults quickly, which is the default for most RCCB applications unless selectivity with downstream devices is needed.
The IP20 finger-safe enclosure is standard for enclosed distribution boards; the IP40 rating applies when mounted in a modular enclosure. The toggle control and padlocking option allow lockout/tagout for maintenance.
