The Schneider Electric A9C62263 is a Reflex iC60N integrated control circuit breaker from the Acti9 range — a 2-pole, 63 A, curve C thermal-magnetic MCB with a built-in control interface, rated for 230 V AC networks at 50/60 Hz. It combines overcurrent protection with remote and local switching: the control type supports ON/OFF button, remote control by pulse, remote control by continuous command, and toggle — so it can be wired into a building management system or used as a local disconnect with a maintained or impulse signal. The breaking capacity is 20 kA Icu at 220...240 V AC and 10 kA Icu at 380...415 V AC, both conforming to EN/IEC 60947-2 — that means it can safely interrupt fault currents up to those levels without welding contacts or cascading failure upstream.
Depth is 77 mm, height 84 mm — check your enclosure depth before committing the BOM line, especially in shallow gland-plate layouts. IP20 protection per IEC 60529 means it is touch-safe but not sealed against water ingress; suitable for dry indoor panels, not washdown zones.
Control and signalling
Control circuit voltage options cover 230 V AC, 24 V AC, 48 V AC, 24 V DC, and 48 V DC — so it can be driven from a standard AC control transformer or a 24 V DC PLC output without an interposing relay. Local signalling includes a flashing LED for device tripped, device ready, device overheat, and a green LED for device ON, plus a red LED for fault — useful for quick visual diagnostics on the panel door. A contact position indicator and provision for padlocking in the OFF position (padlockable) support lockout/tagout procedures during maintenance.
Durability and environment
Electrical durability is 50,000 cycles under AC-1 resistive load at 50 Hz; mechanical durability matches at 50,000 cycles — this is a switch rated for regular operation, not just backup protection. Tropicalisation class 2 and 93 % relative humidity at 40 °C mean it handles warm, humid panel environments without derating — relevant for SEA or coastal installations. Earth-leakage protection is handled by a separate block (not integrated), so if RCD functionality is needed, budget for an external Vigi module.
