Switch-disconnector for control and isolation
The Schneider Electric A9S70663 is an Acti9 iSW-NA switch-disconnector, 1P + N poles, rated 63 A at 230/240 V AC 50/60 Hz. It is designed for control and isolation applications, confirmed by its AC-22A utilisation category per EN/IEC 60947-3, meaning it handles switching of mixed resistive and inductive loads including moderate motor loads. The part is certified for isolation suitability per the same standard, giving a visible break and positive contact indication.
Rated operational current of 63 A at 230/240 V AC defines the continuous load it can carry in normal service. The AC-22A rating confirms it can switch mixed loads up to that current — not just resistive heating, but also moderate motor and transformer inrush. Rated short-time withstand current (Icw) is 1.26 kA for 1 second, and short-circuit making capacity (Icm) is 5 kA when used alone — this tells you the switch can close onto a fault up to 5 kA without welding contacts, and can withstand a through-fault of 1.26 kA for one second while upstream protection clears it. Impulse withstand voltage (Uimp) of 6 kV gives confidence in surge environments typical of industrial panels.
Tunnel-type terminals accept 1 to 35 mm² rigid or 1 to 25 mm² flexible with or without ferrules; strip length 14 mm, tightening torque 3.5 N·m. Compatible with comb busbars top or bottom for daisy-chaining multiple devices in a distribution board. IP20 finger-safe protection, suitable for enclosed panel use.
