The C1036M080 is a MicroLogic 6.2 E-M electronic trip unit from Schneider Electric's ComPacT NSX100...250 range, designed for motor protection in an AC network. It carries LSIG protection — long-time, short-time, instantaneous, and ground-fault — with an electronic trip unit rated 80 A at 65 °C and a maximum operational voltage of 690 V AC at 50/60 Hz.
The 80 A rating at 65 °C (Ir adjustment range 35–80 A) sets the continuous current the trip unit can carry in a warm panel — if your motor FLA is 75 A and ambient hits 65 °C, this unit handles it without derating. The LSIG protection covers overload (L), short-time short-circuit (S) with fixed delay, instantaneous (I) fixed at a multiple of Ir, and ground fault (G). For motor duty, the trip unit supports tripping classes 5, 10, 20, and 30, selectable via the long-time delay adjustment (e.g., 120 s at 1.5 x Ir for class 5, up to 720 s at 1.5 x Ir for class 30). That means you match the thermal curve to the motor's starting profile — a high-inertia load gets class 30 to avoid nuisance trips during start. The short-time pickup (Isd) is adjustable across 9 settings from 5 to 13 x Ir, giving you selectivity headroom downstream. Zone selective interlocking (ZSI) is included — when multiple breakers are daisy-chained, ZSI lets the faulted unit trip instantly while upstream breakers hold, reducing arc-flash energy and keeping the rest of the line running. The LCD display shows energy metering, protection settings, time-stamped events, and maintenance indicators, so you can read trip cause and load data without a laptop.
This trip unit mounts into a fixed ComPacT NSX100...250 circuit breaker (3-pole, 3D protected poles). IP40 front-of-panel protection means it's splash-resistant in a standard enclosure, but not washdown-rated. The trip unit communicates protection and metering data — energy, demand values, power quality, max/min readings — so it can feed a BMS or PLC over the breaker's communication bus. No earth-leakage module is included (ground fault is via the LSIG G function, not a separate RCD).
