The Schneider Electric LC1E50F7 is a three-pole contactor from the Easy TeSys Control range, rated for motor control in AC-3 and AC-3e duty at 50 A up to 440 V, with a 110 V AC 50/60 Hz coil. It is also listed for resistive loads under AC-1. The part is now classified as obsolete by the manufacturer. The 110 V AC coil is common in North American control circuits; verify your control transformer matches before wiring.
Lifecycle reality — obsolete, not gone
Schneider has marked the LC1E50F7 as obsolete. If you are a quality-doc controller tracking a change, note that the LC1E50F7 carries EN/IEC 60947-4-1 (contactor standard) and EN/IEC 60947-5-1 (control circuit device), plus GB/T equivalents. TH protective treatment per IEC 60068-2-30 covers humid environments.
The contactor is designed to make and break those starting currents without welding. For resistive loads (AC-1), the same poles can carry a higher current, but the exact figure is not listed here. This matters for interlocking circuits where a momentary overlap could short phases — the 1.5 ms window ensures the NC set opens before the NO set closes, and vice versa.
