That 1600 A rating at 50 °C sets the continuous current limit for the main bus or feeder it protects — sized for a large distribution board feeding multiple downstream panels or a heavy industrial load. The MicroLogic 5.0 A trip unit provides LSI protection: long-time overload (L), short-time short-circuit (S), and instantaneous short-circuit (I). The electronic trip means you can adjust the pickup and time-delay settings on-site via the LCD display without swapping trip units. Thermal memory holds for 20 minutes after a trip, preventing immediate reclose into a still-hot cable — a detail that matters when coordinating with downstream breakers on a motor-starting or welding load. Mounts fixed to a backplate with a 70 mm connection pitch — standard for panel builders running busbars or cable lugs. Front connections top and bottom simplify busbar runs in a switchboard lineup. IP40 enclosure protection and IK07 impact resistance suit indoor distribution panels where occasional tool contact is expected. ## Integration notes At 327 mm high, 280 mm wide, and 147 mm deep, the C160N45AFM occupies a standard fixed-mount footprint for a 1600 A frame. The 70 mm connection pitch matches common busbar drilling patterns. Front connections top and bottom allow straight-through bus runs or cable ladders without rear access. The LCD display and four red fault-indication LEDs plus one yellow overload LED give visible status without opening the door — useful during commissioning and fault-finding. Power dissipation is 74 W at rated current — account for that heat in the enclosure sizing if the breaker is enclosed rather than open-mounted. The 20-minute thermal memory means the trip unit remembers the thermal state after a trip; if you clear the fault and reclose within that window, the breaker will trip sooner on the next overload because the cable is still hot. That is intended to prevent re-energizing a damaged circuit.","metaTitle":"Schneider Electric C160N45AFM ComPacT NS, 1600 A, 4P, 50 kA","metaDescription":"Schneider Electric C160N45AFM ComPacT NS new generation circuit breaker. 1600 A rating, 4 poles, 50 kA breaking capacity at 415 V AC.
