The Schneider Electric A9C61263 is a Reflex iC60N integrated control circuit breaker from the Acti9 range — a 63 A, 2-pole (2P), curve B thermal-magnetic MCB that also handles remote control functions. It's designed for distribution and control applications, combining overcurrent protection with the ability to switch loads via pulse, maintained, or toggle commands at 230 V AC control voltage. IP20 rated, so it lives inside an enclosure, not exposed to washdown.
Breaking capacity: 20 kA Icu at 230 V AC and 10 kA Icu at 400 V AC, both per EN/IEC 60947-2. Rated current 63 A, curve B. Curve B trips magnetically at 3–5× In (roughly 189–315 A), which suits resistive and lighting loads where inrush is low — not for motor starts. Thermal-magnetic trip unit handles both overload (thermal bimetal) and short-circuit (solenoid) protection in one package. Control flexibility: accepts maintained, impulse, or toggle signals at 24 V AC/DC, 48 V AC/DC, or 230 V AC. That makes it usable with PLC digital outputs, pushbuttons, or a building management system's remote trip signal. Electrical durability rated 50,000 cycles at AC-1 resistive load — solid for frequent switching in lighting or HVAC contactor-replacement roles.
Dimensions: 84 mm high, 81 mm wide, 77 mm deep. Occupies 9 mm pitches on the DIN rail — standard for a 2P MCB in the Acti9 family.
