This part is officially obsolete per the manufacturer. If you're designing a new panel, the Acti9 range still carries active 3P 125 A D-curve MCBs; check the latest catalog for the current order code that matches your duty. The same 15 kA Icu under IEC 60947-2 means it also meets the industrial standard for isolation and performance after fault interruption. The 125 A rating at 30 °C is the continuous current; derate for higher ambient temps per the thermal curve. The D-curve magnetic trip at 10–14× In (1,250–1,750 A instantaneous) is the key selection parameter for motor or transformer primary protection — it avoids nuisance trips on inrush while still clearing short circuits fast enough for cable protection. ## Panel Integration & Compliance Mounts on standard DIN rail via clip-on, 9 mm pitch per pole — 3 poles means 27 mm of rail width. The toggle handle gives local ON/OFF indication and a contact position indicator for isolation verification (suitable for isolation per the spec). Tunnel terminals accept 1–50 mm² rigid or 1.5–35 mm² flexible, torqued to 3.5 N·m. Compliance covers GB 10963.1, EN/IEC 60898-1, GB/T 14048.2, and EN/IEC 60947-2 — so it's accepted in both residential-distribution (60898) and industrial (60947) applications across Europe, China, and markets that follow those standards. Rated insulation voltage 500 V AC, impulse withstand 6 kV.","metaTitle":"A9N19862 Acti9 C120L MCB 3P 125A D Curve 15kA","metaDescription":"Schneider Electric A9N19862 Acti9 C120L miniature circuit breaker. 3-pole 125A D curve 15kA breaking capacity at 400V AC.
