The MicroLogic 2.0 electronic trip unit provides L (long-time overload) and I (instantaneous short-circuit) protection curves — no ground-fault module on this variant. Breaking capacity hits 85 kA Icu at 240 V AC and 50 kA Icu at 415 V AC, both per IEC 60947-2, so it handles high-fault utility feeds without cascading upstream. Front-connect terminals on a 70 mm pitch simplify busbar alignment in a fixed-backplate layout. At 690 V AC the Icu drops to 30 kA — still enough for most industrial loads, but verify against the transformer impedance if you're feeding a 690 V bus. Category B utilisation means the breaker is designed for selectivity with downstream breakers; the short-time withstand (not explicitly listed here but implied by Cat B) allows delayed tripping on a fault so the downstream device clears first. ## Lifecycle and sourcing — active production, no LTB watch needed The C160N420FM carries a current lifecycle stage from the manufacturer — no phase-out notice, no last-time-buy window. This is a standard catalogue item in the ComPacT NS new generation family, which Schneider continues to develop and support. ## Mounting and integration — fixed-backplate, front-connect Fixed-mount on a backplate, not DIN-rail. The 280 mm width and 327 mm height need a cutout sized for the ComPacT NS630b–1600 footprint; the 70 mm connection pitch matches standard busbar drilling for 1600 A class. Front-connect terminals on both upside and downside keep cabling accessible in a row of fixed breakers. IP40 enclosure protection means it's suited for indoor switchboard cubicles — not washdown or outdoor without an additional enclosure. IK07 impact rating handles accidental tool strikes during panel assembly.","metaTitle":"C160N420FM ComPacT NS 1600A 4P Circuit Breaker, MicroLogic 2","metaDescription":"C160N420FM ComPacT NS new generation 1600A 4P circuit breaker with MicroLogic 2.0 electronic trip unit. 85 kA Icu at 240V AC, EN/IEC 60947-2.
