The LC1F185D7 is a 3-pole TeSys F contactor from Schneider Electric, rated for switching motor loads up to 185 A in AC-3 duty (≤440 V) — that's the current it can make and break under the inductive load of a squirrel-cage motor during starting and running. At 380-400 V AC, that translates to 90 kW motor power; at 415 V it handles 100 kW, and at 500 V it still delivers 110 kW. The 42 V AC control coil (40-400 Hz) pulls 1070 VA inrush and holds at 9.9 VA, with a dropout range of 0.2-0.55 Uc — useful to know if you're integrating into a control transformer circuit with voltage sag. The contactor also carries AC-1 (resistive load) and AC-4 (plugging/inching) ratings, with a rated breaking capacity of 1480 A per IEC 60947-4-1. The 0.33 mOhm average impedance at 275 A Ith means heat dissipation runs 8-9.8 W total, or 12 W per pole in AC-3 and 25 W per pole in AC-1 — factor that into your panel thermal budget.
This part is end-of-life hot (EOL hot) — Schneider has discontinued production and the last-time-buy window is closed or closing.
