The Schneider Electric LC1E3801B7 is a 3-pole contactor from the Easy TeSys Control range, rated 38 A in AC-3 and AC-3e utilization categories at up to 440 V. This is the part you spec when the BOM calls for a standard motor-switching contactor on a 24 V AC control circuit — no surprises, no special-order lead time.
The 38 A AC-3 rating is the motor-switching current — it handles starting and running of a three-phase induction motor up to that load. AC-3e is the same duty but with an extended electrical life profile for high-cycle applications. The 24 V AC coil is common in older control systems and some export panels. The 50/60 Hz compatibility means it works on either mains frequency without a coil change. The 1.5 ms guaranteed non-overlap time between NC and NO contacts prevents a momentary short-circuit when switching between the two — important for reversing or star-delta starter circuits. The IP2X finger protection is standard for enclosed panels — no special handling for live parts.
The 56 mm width means it takes three modules of space — plan your DIN rail fill factor accordingly. The 1.5 ms non-overlap time is baked into the contactor's mechanical interlock — no external timing relay needed for basic NC/NO separation. For reversing applications, pair two of these with a mechanical interlock accessory.
Compliant with EN/IEC 60947-1, 60947-4-1, and 60947-5-1 — the core contactor and control circuit standards. Also meets GB/T 14048.1/4/5 for Chinese market installations, and EN/IEC 60335-1 Clause 30.2 and 60335-2-40 Annex JJ for appliance and HVAC applications.
