The Schneider Electric LC1E80004Q7IN is a 4-pole (4NO) power contactor from the Easy TeSys Control range, rated for AC-1 resistive loads at 110 A up to 415 V. It's built for switching resistive heater banks, lighting banks, or other non-inductive loads where inrush is minimal — the AC-1 utilisation category tells you this isn't the part for motor starting (that's AC-3).
Lifecycle reality — this part is obsolete
The LC1E80004Q7IN is officially obsolete per the manufacturer. That means no further production runs — no factory orders, no standard lead time.
The AC-1 rating of 110 A at ≤415 V is the continuous resistive current the main poles can carry and break. The 4P (4NO) configuration gives four normally-open power poles. Mechanical robustness is specified for vibration (1.5 Gn open, 3 Gn closed) and shock (6 Gn open, 7 Gn closed), which is typical for panel-mounted contactors in industrial environments — not a limiting factor for stationary installs. Ambient temperature range of -20 to 70 °C at coil rated voltage, with operation limited to -5 to 55 °C, means it's fine for a ventilated enclosure but watch the derating if it's packed next to a heat source. The 850 °C glow-wire test per IEC 60695-2-1 and pollution degree 3 (TH treatment) mean it's rated for typical industrial panel environments with conductive dust or condensation.
IP2X means finger-safe terminals, but no washdown rating; keep it inside the panel.
