It's the brain that decides when to hold, when to trip, and what data to log — rated 250 A at 40 °C for 4-pole distribution feeders. This is the version with integrated earth-leakage protection (Class A) and full LSIR curves: long-time, short-time, instantaneous, and residual current. The Ir adjustment range (100–250 A) lets you down-rate the trip point to match the actual load without swapping hardware, critical when a feeder is oversized for future expansion but needs to protect today's 180 A load. LSIR protection means you get four coordinated curves: L (long-time, adjustable 15–400 s at 1.5×Ir) for overload, S (short-time, 0–0.4 s with I²t on/off) for selective coordination downstream, I (instantaneous, adjustable) for bolted faults, and R (earth-leakage, integrated Class A) for ground faults. The 20-minute thermal memory before and after tripping means a reclose after a near-trip won't let the next overload cook the cable — the trip unit remembers the heat history. Neutral protection settings are selectable: 0.5×Ir (3D+N/2), 1×Ir (4D), 1.6×Ir (3D+OSN), or no protection. ## Deployment context This trip unit snaps into a ComPacT NSX250 fixed-mount breaker in a distribution panelboard or switchboard. The IP40 front face (IEC 60529) is fine for indoor electrical rooms but not washdown areas — keep it dry. The LCD display shows real-time energy metering, demand current, power quality, and event logs, so you can read load profiles without a separate meter or gateway. Current production — the MicroLogic 7.2 E is an active catalog item in Schneider's ComPacT NSX line. No end-of-life notice on this variant.","metaTitle":"C2547E250 ComPacT NSX MicroLogic 7.2 E Trip Unit, 250 A","metaDescription":"Schneider Electric C2547E250 ComPacT NSX250 trip unit, MicroLogic 7.2 E, 250 A, 4P, LSIR protection with integrated earth-leakage.
