The Schneider Electric A9S70780 is an Acti9 iSW-NA switch disconnector with 3P + N poles, rated 80 A at 400/415 V AC 50/60 Hz. It is classified under utilisation category AC-22A per EN/IEC 60947-3, meaning it is designed for switching mixed resistive and inductive loads, including moderate motor loads, at rated current. The device is also certified for isolation use, with a contact position indicator and ON/OFF local signalling.
For isolation duty, the suitability is confirmed by the standard, so it can be used as a visible-break disconnector in a panel. The rated short-time withstand current (Icw) is 1.2 kA for 1 second, and the short-circuit making capacity (Icm) is 5 kA alone — these tell you the switch can handle fault conditions without welding contacts, but it is not a circuit breaker; upstream protection must coordinate. The pollution degree 3 rating (IEC 60947-3) indicates it can tolerate conductive pollution in industrial environments, which is typical for switchgear in factory settings.
The comb busbar compatibility (top or bottom) simplifies distribution wiring in a panel.
