It complies with IEC 60669-1 and IEC 60947-3, rated for AC-22 utilisation category — meaning it handles mixed resistive and inductive loads, typical for general distribution isolation. The 2.5 kA rated breaking capacity suits it for downstream isolation where fault levels are moderate. ## Sourcing reality — obsolete part Schneider has marked the A9S2P100 as obsolete. The 2-module 18 mm footprint and 100 A AC-22 rating are the specs to match if evaluating a drop-in from another manufacturer's range. The 100 A rating at 240 V AC is the headline — this isolator handles full panel feed or large subfeed isolation. The 2.5 kA breaking capacity is not a high-fault device; it's intended for isolation, not fault clearing upstream of a breaker. The DC rating is split: 48 V DC for single-pole use, 100 V DC for both poles in series — useful for battery-bank or DC distribution isolation. The 500 V impulse withstand and 6 kV rated insulation voltage give it headroom for 400 V AC systems with typical surge environments.","metaTitle":"A9S2P100 Acti9 ISW 2P 100A Isolator, Obsolete","metaDescription":"A9S2P100 Acti9 ISW 40...125 2P 100A isolator, 2.5 kA breaking capacity, IEC 60947-3.
