The Schneider Electric A9Z25480 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 iID series, rated at 80 A with 300 mA earth-leakage sensitivity and Type A protection — meaning it trips on sinusoidal AC and pulsating DC residual currents, which covers most modern electronic loads like VFDs, switched-mode supplies, and LED drivers. The selective (S-type) time delay prevents nuisance tripping on short-duration leakage pulses, so this unit coordinates downstream with faster RCCBs or RCBOs in a distribution board. Rated operational voltage is 380...415 V AC at 50/60 Hz, with a conditional short-circuit current (Icc) of 10 kA — enough for typical commercial and light industrial panels where the upstream breaker provides the fault clearance. The voltage-independent tripping mechanism means it operates without an external power supply, so a loss of neutral or line voltage won't disable the earth-leakage protection. The IP20 finger-safe terminals (IP40 in modular enclosure) suit indoor panel use.
The A9Z25480 is current-production in the Schneider Electric Acti9 range. No end-of-life notification or successor order code is on record. Compliance documentation covers EN/IEC 61008-1 and EN/IEC 61008-2-1 for RCCB performance and safety. The 8/20 µs impulse withstand of 3000 A per EN/IEC 61008-1 confirms the unit's immunity to surge currents from lightning or switching transients.
Integration notes
The toggle control and contact position indicator give a clear visual of the mechanical state, and the padlocking device allows lockout/tagout in the off position. Mechanical durability is rated at 20000 cycles; electrical durability under AC-1 resistive load is 10000 cycles. Storage temperature range is -40...85 °C, operating range -25...60 °C — acceptable for most indoor panel environments.
