What it is and what it does
The LC3D80Q7A64 is a TeSys D star delta starter from Schneider Electric, pre-wired for motor starting duty. It carries 3 x 3P (3 NO) power poles rated at 80 A in the AC-3 utilisation category — the standard for squirrel-cage motor switching during start-up and run. The 380 V AC coil is built into the assembly, so this is a drop-in unit for a star-delta scheme, not a bare contactor you wire up yourself. AC-3 rating at 80 A means it handles the inrush and break of a motor load up to that current without welding or excessive wear. For a 380 V supply, that typically covers motors in the 37–45 kW range depending on service factor — a common size for pumps, fans, and compressors on a bottling or process line.
Where it goes and what it tolerates
This starter is built for panel mounting with an IP2X front face — finger-safe from the front, but the enclosure it lives in handles the washdown. The operating range is -40 to 60 °C, with derating allowed up to 70 °C, so it works in a hot panel next to a drive or transformer. Storage tolerance from -60 to 80 °C covers shipping and warehouse extremes. Pollution degree 3 means it's rated for conductive pollution or dry non-conductive pollution that becomes conductive due to condensation — typical for industrial control panels not in a cleanroom. The TH protective treatment per IEC 60068-2-30 confirms it withstands damp heat cycling, so it's fine in humid environments like a beverage line or brewery. Fire resistance at 850 °C per IEC 60695-2-1 and V-1 flame retardance per UL 94 mean the housing won't propagate a flame in a fault scenario — important for panel builders needing UL 508A compliance on the overall assembly.
