The 1600 A continuous rating governs the busbar and cable sizing upstream — this breaker does not derate at 50 °C, so the full 1600 A is available at that ambient. The MicroLogic 5.0 electronic trip unit provides LSI protection: long-time overload (L), short-time short-circuit (S) with adjustable time delay for selectivity, and instantaneous (I) for fault clearing. Utilisation category B means the breaker is suitable for distribution with no special current-limiting requirements upstream. Mounts fixed to a backplate (mounting support: backplate). Front-connected on both upside and downside — all cable or busbar terminations are accessible from the front, which simplifies panel layout and gland-plate planning. Connection pitch is 70 mm, matching standard busbar spacing for 1600 A class breakers. Dimensions: 327 mm high, 280 mm wide, 147 mm deep — verify enclosure depth and door clearance before committing the cutout. IK07 impact protection (EN 50102) covers incidental mechanical shock during installation. ## Selectivity and protection coordination The MicroLogic 5.0 trip unit's LSI curves allow full selectivity with downstream breakers. The S (short-time) protection has adjustable time delay and I²t on/off — critical for cascading coordination in a distribution tree. Thermal memory of 20 minutes means the trip unit remembers the thermal state of the breaker after a trip, preventing immediate reclose on a hot conductor. Electrical durability: 1000 cycles at 690 V In, 2000 cycles at 690 V In/2, 2000 cycles at 440 V In, 5000 cycles at 440 V In/2. Mechanical durability: 10 000 cycles. Power losses are 74 W at rated current — factor this into enclosure ventilation calculations. No earth-leakage protection built in (without); if ground-fault protection is needed, specify a separate module or a MicroLogic 6.0/7.0 trip unit instead.","metaTitle":"Schneider Electric C160N450FM ComPacT NS 1600A, 50kA 415V AC","metaDescription":"Schneider Electric C160N450FM ComPacT NS new generation circuit breaker. 1600 A, MicroLogic 5.0 trip unit, 4P, 50 kA Icu at 415 V AC.
