Rated 25 A at 50 °C, so no derating headache in a warm enclosure as long as ambient stays under that. The 100 mA earth-leakage threshold is a common choice for circuits supplying equipment where nuisance tripping from a 30 mA device would be a problem — think fixed machinery, lighting banks, or sub-distribution where personnel contact is unlikely but ground-fault protection is still code-required. ## Panel integration The tunnel-type terminals accept 1 to 16 mm² rigid cable (1 to 10 mm² flexible with or without ferrule), and the tightening torque is 2 N·m. Wire strip length is 13 mm. IP20 rated — fine for a distribution board or enclosed panel, not for wet environments. Padlockable with a Ø4 mm padlock for lockout/tagout. Rated for 5,000 electrical cycles and 20,000 mechanical cycles. That is a standard duty class for a distribution RCBO — not a heavy-switching device, but adequate for its role as a protective device that operates only under fault or manual isolation. The toggle provides ON/OFF indication and a contact position indicator confirms the state of the main contacts.","metaTitle":"Schneider Electric A9D18825 IKQE RCBO, 25 A, 100 mA, Curve C","metaDescription":"Schneider Electric A9D18825 Acti9 IKQE RCBO, 1P+N, 25 A rated, 100 mA earth leakage, curve C, 10 kA breaking capacity.
