The 85 kA Icu at 240 V AC (50/60 Hz) per IEC 60947-2 tells you this breaker can safely interrupt a fault current up to that level without welding or rupturing — that's the short-circuit withstand that decides whether it holds on a high-fault panel or lets the arc flash through. At 415 V AC the same rating drops to 50 kA Icu, which is still a strong number for a 400 A frame; at 690 V AC it holds 10 kA Icu, enough for most 690 V distribution but not for high-fault motor centers at that voltage. The MicroLogic 7.3 E trip unit gives you four protection curves in one package: L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and R (earth-leakage). That means this single breaker covers both overcurrent and ground-fault protection without an external relay — a common spec for main or feeder breakers where you need coordinated tripping downstream. The trip unit is electronic, so it holds its curve tighter than a thermal-magnetic over temperature swings, and it includes thermal memory that remembers the last 20 minutes of heating before and after tripping, which prevents nuisance reclose on a hot cable. The LCD display on the front gives you local readout of instantaneous and demand values, energy metering, and time-stamped event histories — useful for a panel that doubles as a sub-metering point. The toggle control and the IΔn rotary switch for earth-leakage OFF position let an operator isolate the R function without killing the main breaker, which is handy during commissioning or fault-finding. Neutral is on the left, which matters when you're laying out bus bars or cable ladders — mirror the arrangement if you're replacing an older frame with neutral on the right. The 45 mm connection pitch is standard for busbar tap-offs in this frame size. Availability and current pricing are confirmed at quote time — the 400 A frame and MicroLogic 7.3 E are common enough that lead times tend to be reasonable, but the N breaking capacity (50 kA at 415 V) is a specific variant that may not sit on every distributor's shelf.
