The A9F77616 is a 1P+N miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, designed for single‑phase AC installations where neutral protection is not required. Rated at 16 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In), this device protects the phase conductor while the neutral is switched only, offering a space‑saving and economical alternative to full 2‑pole breakers. The C‑curve delivers a well‑balanced response, ensuring reliable overload and short‑circuit protection while tolerating moderate inrush currents from lighting, socket outlets, and small appliances in residential and commercial settings. With an ultimate breaking capacity of 10 kA at 220‑240 V AC (IEC 60947‑2) and 6 kA at 230 V AC (IEC 60898‑1), it clears faults effectively in typical low‑voltage distribution boards. The breaker is dual‑certified to both industrial and residential standards, making it a flexible choice for mixed‑use projects. It features the VisiTrip indicator, which visually pinpoints the tripped pole for rapid fault identification, and the VisiSafe green strip that provides a clear, physical indication of contact opening – an indispensable safety feature for downstream work. The quick‑make/quick‑break mechanism, independent of the toggle position, ensures long‑term reliability over 10,000 electrical and 20,000 mechanical cycles. Its 36 mm width (4 modular pitches) fits standard DIN‑rail enclosures, and the double‑tunnel terminals accept conductors up to 25 mm² (rigid) and 16 mm² (flexible) with a 2 N·m torque. Operating from -35 °C to +70 °C, the device is built with PVC‑free materials and achieves 54% recyclability, though it contains halogen above thresholds. Its total lifecycle carbon footprint is 28 kg CO₂ eq., reflecting Schneider Electric’s commitment to environmental transparency.
