The Schneider Electric LC1E3801P7 is a 3-pole contactor from the Easy TeSys Control range, rated for 38 A in AC-3 and AC-3e utilisation categories at voltages up to 440 V. The coil is 230 V AC, and it carries one normally-closed auxiliary contact for status feedback or interlocking. It is designed for motor control and resistive load switching, with a mechanical life backed by vibration and shock ratings: 1.5 Gn on the open contactor, 3 Gn when closed, and 10 Gn shock survival for 11 ms on the closed contacts.
That depth is the dimension from the mounting surface to the furthest projection — relevant when sizing a shallow enclosure or planning clearance behind a gland plate. This prevents a momentary short-circuit condition when switching between contact sets in reversing or star-delta starters.
It also meets GB/T 14048.1, 14048.4, and 14048.5 for the Chinese market, plus EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for appliance applications.
