It provides LSI protection (long-time, short-time, instantaneous) with adjustable settings, plus integrated power metering and an LCD display (128 x 96 pixels) for local readout of currents, voltages, power, energy, harmonics, and event logs. Rated for use with MasterPacT frames, the trip unit is configurable for 3-pole or 4-pole breakers and supports a wide range of sensor ratings from 400 A up to 6300 A. That means one control unit can be specified across multiple breaker frame sizes, simplifying BOM management. ## Protection and metering in one package The LSI protection suite covers overload (long-time, ANSI 49), short-time short-circuit (ANSI 51), and instantaneous short-circuit (ANSI 50). Long-time pickup is adjustable from 0.4 to 1 x In in 1 A steps, and the long-time delay can be set between 12.5 and 600 s at 1.5 x Ir. Short-time delay is also adjustable, and zone selective interlocking (ZSI) is included for tighter coordination between downstream breakers. Beyond protection, this unit functions as a power meter with Class 0.5 accuracy on voltage and current, and Class 1 on active energy. It measures all standard electrical parameters — per-phase and total — including THD, unbalance, earth leakage, and demand values. The data recording includes event logs, min/max values, alarm logs, and maintenance logs with time stamping. ## Communication and diagnostics For local configuration and data retrieval, the MicroLogic 5.0 X includes Bluetooth 4.0 LE, NFC, and a USB port. The diagnostics suite goes beyond simple trip cause indication — it tracks breaker health state, MicroLogic service life, contact state, and provides a system health overview. Protection and selectivity tests can be run from the HMI, and trip context data is available for post-event analysis. Designed for distribution applications per IEC standards, the LV839222 complies with EN/IEC 60947-2 (circuit breakers), EN/IEC 60255-1 (measuring relays), and EN/IEC 60092-202 (marine electrical installations). The unit can be mounted at altitudes up to 5000 m with voltage derating above 560 V AC.","metaTitle":"Schneider Electric LV839222 MicroLogic 5.0 X Control Unit, M","metaDescription":"LV839222 MicroLogic 5.0 X electronic trip unit for MasterPacT breakers.
