The Schneider Electric A9S2P080 is an Acti9 ISW series 2-pole isolator rated 80 A at 240 V AC, with a 2.5 kA rated breaking capacity under AC-22 utilisation category. It is designed for isolation duty in distribution boards, occupying 2 x 18 mm DIN-rail modules.
This part is obsolete per the manufacturer's lifecycle status.
The 80 A rated operational current at 240 V AC (AC-22) governs mixed resistive and inductive loads, typical for distribution board isolation switching. The 2.5 kA breaking capacity under AC-22 is the fault-clearing capability the isolator can safely interrupt — verify this coordinates with upstream protective devices in your selective scheme. The 6 kV rated insulation voltage and 500 V impulse withstand voltage support installation in 400 V class systems with adequate clearance. The DC supply voltage rating is 48 V DC for 1-pole use and 100 V DC for 2-pole use — relevant if this isolator is applied in a DC bus or control circuit isolation role, not just AC distribution.
Certified to IEC 60947-3 (low-voltage switchgear, isolators) and IEC 60669-1 (switches for household and similar fixed electrical installations).
