The Schneider Electric A9Z32480 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 iID family, rated for 80 A continuous current at 380-415 V AC 50/60 Hz. Clip-on DIN rail mounting and a 72 mm width mean it occupies four 18 mm modular pitches — standard for a 4P RCCB in a distribution board.
Integration into the enclosure
The 73 mm depth fits standard modular enclosures; the 91 mm height is within the usual cut-out for a four-module-width device. The IP20 rated body suits dry indoor panels; an IP40 rating is achieved when installed in a modular enclosure.
The 6 kV rated impulse withstand voltage and pollution degree 3 confirm suitability for industrial distribution panels where transient overvoltages and conductive contamination are expected. The voltage-independent tripping mechanism means the device clears a ground fault even if the phase voltage is lost — a critical safety feature for circuits where loss of neutral could otherwise mask a fault.
