The coil is 24 V AC, 50 Hz — so it's a fixed-frequency part, not a 50/60 Hz universal coil. That matters when you're ordering spares for a line running on 50 Hz only; a 60 Hz coil would pull a different inrush and might drop out early. The contactor carries IP2X finger protection on the enclosure, and the TH treatment per IEC 60068-2-30 means it's protected against tropical humidity — fine for most industrial environments short of direct washdown. If you're using the NC mirror contact for safety feedback, that 1.5 ms window is what prevents a short overlap that could confuse a safety relay. The contactor is 132 mm deep, 120 mm wide, 158 mm high — a compact footprint for a 120 A device. The 3P (3NO) configuration gives you three normally-open main poles; there's no built-in auxiliary contact block, so you'll add a side-mount block if you need feedback or a holding circuit. That 55 °C ceiling is typical for contactors in a ventilated enclosure; if your panel runs hotter, you'll need to derate or add forced air. Altitude rating is 3000 m without derating, which covers most installations outside high-altitude mining or ski-lift applications. For compliance documentation, Schneider provides declarations of conformity covering the IEC standards listed. RoHS and REACH compliance are standard for the Easy TeSys line, but the specific certificates are issued per production batch — your quality team can request them with the order. ## Sourcing note This part is active and widely specified. The 24 V AC 50 Hz coil is the main differentiator from the more common 24 V DC or 50/60 Hz variants; make sure your control transformer matches.","metaTitle":"Schneider LC1E120B5 Easy TeSys Contactor, 120A AC-3, 24VAC 5","metaDescription":"Schneider Electric LC1E120B5 Easy TeSys Control contactor, 3P(3NO), AC-3 120A at 440V, 24V AC 50Hz coil.
