The A9F83216 is a 16‑ampere, double‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, engineered with a B‑curve tripping characteristic (magnetic threshold at 4 × In). The B‑curve is specifically designed for circuits with minimal inrush currents – such as lighting, resistive loads, and general‑purpose distribution – where precise overload protection is essential without nuisance tripping. As a 2‑pole device with both poles protected, it is ideally suited for single‑phase AC systems or DC applications requiring simultaneous disconnection of both lines, offering enhanced safety and isolation. This MCB delivers a rated ultimate breaking capacity of 30 kA at 220‑240 V AC under the industrial EN/IEC 60947‑2 standard, and 10 kA at 400 V AC per the residential EN/IEC 60898‑1 norm, ensuring robust fault interruption across a wide range of applications. It is certified to both standards, making it a versatile choice for commercial distribution boards, industrial control panels, and residential consumer units. Designed with Class‑2 insulation for enhanced operator safety, the breaker also coordinates seamlessly with Acti 9 RCDs and Compact NSX MCCBs. The device incorporates the intuitive VisiTrip fault‑finder window, which instantly pinpoints the tripped pole to accelerate troubleshooting, and the VisiSafe green strip that delivers unmistakable visual confirmation of contact opening – a critical safety feature for maintenance operations. Its quick‑make/quick‑break mechanism, independent of toggle position, guarantees consistent switching performance over 10,000 electrical and 20,000 mechanical cycles. With a width of 36 mm (4 modular pitches) and DIN‑rail clip‑on mounting, it offers efficient space utilisation in distribution panels. The double‑tunnel terminals accept rigid conductors up to 25 mm² and flexible up to 16 mm² with a 2 N·m tightening torque. The device offers IP20 terminal protection and IP40 when enclosed, operates reliably from -35 °C to +70 °C, and is built with PVC‑free materials, though it contains halogen above thresholds. Achieving a 54% recyclability rate and a total lifecycle carbon footprint of 28 kg CO₂ eq., this MCB aligns with Schneider Electric’s sustainability objectives.
