Switch disconnector for control circuits — 63 A, 2P, DIN rail
The Schneider Electric A9KS15263BQ is an Acti9 SW switch disconnector rated 63 A at 415 V AC (AC-22A utilisation category), meaning it handles mixed resistive and inductive loads in control circuits — typical for isolating motor feeders or panel branch circuits under load. Two poles, fixed DIN-rail mount, tunnel terminals accepting up to 35 mm² rigid wire. Set of six units per order.
AC-22A at 415 V is the key duty: this switch disconnector is designed for switching mixed loads — not purely resistive (AC-21) nor motor starting (AC-23). The 63 A rating holds at 415 V, so it's sized for branch circuits up to that current. Short-time withstand (Icw) is 756 A for 300 ms, enough to ride through downstream fault clearing without welding contacts. Impulse withstand (Uimp) at 4 kV per IEC 60947-3 covers standard industrial overvoltage transients.
Width is 36 mm (2 modular spaces at 18 mm each), depth 74 mm, height 81 mm — fits a standard distribution board or enclosure. Tunnel terminals upstream and downstream accept 1–35 mm² rigid or 1–25 mm² flexible; strip length 9 mm, torque to 3.5 N·m. IP20 finger-safe front, IP40 inside the enclosure. Pollution degree 2 environment.
