The 25 A [In] is the thermal continuous rating — the RCCB will carry that load indefinitely without tripping. The 100 mA sensitivity means it will disconnect when leakage to earth exceeds that threshold, which is typical for submain or feeder protection where a 30 mA device would nuisance-trip on cable capacitance. Type AC detection covers sinusoidal AC residual currents only; if the installation has rectified or pulsed DC fault currents (common with VFDs, LED drivers, or UPS-fed circuits), a Type A or Type B RCCB is needed instead. The instantaneous trip (no intentional delay) means it clears fast, but selectivity with upstream devices requires a time-delayed S-type RCCB or an MCB/RCCB combination. Insulation voltage is 500 V AC, and operational voltage is 400...415 V AC — this is a 4-pole unit for three-phase + neutral systems, neutral on the left. The 18 mm phase pitch and tunnel terminals accept up to 35 mm² rigid or 25 mm² flexible, with a 3.5 N·m tightening torque. Strip 15 mm for a reliable connection. ## Deployment context The toggle provides ON, OFF, and fault-trip local signalling, and a padlocking device can lock it in the OFF position for isolation (it is suitability-for-isolation certified).","metaTitle":"Schneider Electric A9N16253 Acti9 xID RCCB, 25A, 100mA, 4P","metaDescription":"Schneider Electric A9N16253 Acti9 xID RCCB, 25A rated current, 100mA earth leakage sensitivity, 4-pole, Type AC, 400-415V AC, DIN rail mount, current production.
