This means you select and install the trip unit separately (thermal-magnetic or electronic), so the frame itself is a fixed mechanical base with a 160 A continuous current capacity. The 25 kA Icu at 380/415 V AC (50/60 Hz) per IEC 60947-2 tells you it can safely interrupt a fault current up to that level without failing, which is the standard for commercial and light industrial distribution panels. ## Mounting and integration — fixed backplate, front connections Mounts fixed to a backplate (not DIN rail) with a 35 mm connection pitch. Front-facing upside and downside connections simplify busbar or cable routing in a panel. The 105 mm width, 161 mm height, and 86 mm depth fit standard enclosure layouts for 160 A frames. IP40 front-face protection and IK07 impact resistance suit indoor panel environments. ## Electrical durability and isolation capability Rated for 40,000 mechanical cycles and 40,000 electrical cycles at 440 V AC at rated current (In). At 690 V AC, electrical durability drops to 7,500 cycles at In — expect shorter life on higher-voltage motor loads. The frame is certified for isolation (suitability for isolation per EN/IEC 60947-2), meaning it can be used as a disconnecting means with a visible break.","metaTitle":"Schneider Electric C16B3 ComPacT NSX160B, 160A, 3P, 25kA/415","metaDescription":"Schneider Electric C16B3 ComPacT NSX160B basic frame, 160A at 40°C, 3-pole, 25kA Icu at 415VAC.
