The D curve means magnetic tripping occurs at 10–14 × In (per GB 10963.1) or 12 × In ±20% (per GB/T 14048.2) — designed for loads with high inrush, like motor circuits or transformers, where a B or C curve would nuisance-trip on startup. That dual standard matters: 60898-1 covers household-type installation, while 60947-2 covers industrial panel duty — this one part satisfies both, so it fits a distribution board or an industrial sub-panel without a second look at the standard. Clip-on mounting to DIN rail (9 mm pitches) means it snaps into a standard 3-module width on the rail. The 73 mm depth and 81 mm height keep it within the envelope of a typical Acti9 distribution board — no surprises when you're laying out gland plates or calculating fill factor. ## Integration notes Tunnel-type terminals accept 1–50 mm² rigid (without cable end) or 1.5–35 mm² flexible (with or without ferrule). The toggle gives local ON/OFF indication and a contact position indicator confirms isolation status — useful for a field service tech verifying the circuit is dead before working downstream. Rated insulation voltage 500 V AC, impulse withstand 6 kV. Electrical durability 5000 cycles, mechanical 20,000 cycles — the mechanical figure governs panel life if the breaker is used as a disconnect switch rather than just overcurrent protection.","metaTitle":"A9N19854 MCB Acti9 C120L 3P 100A D Curve, 15 kA","metaDescription":"A9N19854 Acti9 C120L miniature circuit breaker, 3P, 100A, D curve, 15 kA breaking capacity.
