At 690 V AC the rating drops to 45 kA Icu — still sufficient for most 690 V distribution, but the derating curve matters when coordinating with downstream devices. The MicroLogic 5.3 E provides L (long-time overload), S (short-time short-circuit), and I (instantaneous) protection curves. The electronic trip unit includes thermal memory with a 20-minute retention before and after tripping — meaning a reclose after a thermal trip will account for the residual heat in the conductors, preventing nuisance trips on a hot restart. ## Durability and mounting Mechanical durability is rated at 15,000 cycles; electrical durability at 440 V In is 6,000 cycles, halving to 3,000 cycles at 690 V In. These figures govern maintenance intervals in high-cycle applications like conveyor or pump panels. The breaker mounts to a backplate (not DIN rail) and can be installed horizontally or vertically flat on the back — a consideration for enclosure layout and cable entry. Front-facing upside and downside connections simplify busbar or cable routing in a panel. The 45 mm connection pitch matches standard ComPacT NSX busbar systems.","metaTitle":"Schneider Electric C40R45E400 ComPacT NSX 400A, 200kA at 415","metaDescription":"Schneider Electric C40R45E400 ComPacT NSX400R MCCB. 400A at 40°C, MicroLogic 5.3 E trip unit, 200 kA Icu at 415 V AC.
