Product Features
- 40A AC-3 Rating — 30 HP at 480V: The LC1D40 is rated at 40A under AC-3 (motor starting and running) duty, corresponding to 30 HP at 480V three-phase. The AC-1 rating is 60A for resistive or slightly inductive loads such as heating elements.
- Field-Mount Auxiliary Contacts (LA1D Series): The base LC1D40 does not include built-in auxiliary contacts. Add-on LA1D series auxiliary contact blocks mount directly to the front or side of the contactor body for control and signalling circuits. Common options include the LA1DN11 (1 NO / 1 NC), LA1DN20 (2 NO), and LA1DN02 (2 NC). Auxiliary contacts are ordered separately.
- TeSys D / TeSys Deca Series: The LC1D40 is part of the Schneider Electric TeSys D contactor family, now also sold under the TeSys Deca designation. TeSys D is the world’s best-selling line of IEC contactors, known for long mechanical and electrical life, extensive accessory availability, and global certifications.
- DIN Rail or Panel Screw Mounting: Mounts on standard 35mm DIN rail or directly to a panel backplate using the built-in screw-mount feet. IP20 finger-safe terminals are marked with both North American and international terminal designations.
- Direct-Mount Overload Relay Compatibility: The LC1D40 pairs directly with Schneider Electric LRD series thermal overload relays and LR9D series electronic overload relays to form a complete IEC motor starter. The overload relay clips to the bottom of the contactor without additional wiring.
- High Short-Circuit Current Rating (SCCR): The LC1D40 is rated up to 100 kA SCCR when used with appropriate circuit breakers at 480V, providing the flexibility needed for high-fault industrial power systems.
- EverLink Terminal Option: Select LC1D40 variants are available with Schneider’s EverLink BTR screw connector technology, which maintains connection torque over time and reduces maintenance requirements for power terminals. Check individual variant listings for availability.
- Global Certifications: UL Listed, CSA Certified, IEC 60947-4-1, and CE marked for worldwide installation compliance.

Frequently Asked Questions
What is the HP rating of the LC1D40?
The LC1D40 is rated at 30 HP at 480V three-phase under AC-3 motor duty. At 230V three-phase, the rating is 20 HP. At 575V, the rating is 40 HP. Always select the HP rating based on your motor’s supply voltage. Note that some older references list the LC1D40 at 20 HP — this reflects a lower or different voltage basis. The current Schneider Electric rating is 30 HP at 480V.
Does the LC1D40 come with built-in auxiliary contacts?
No — the base LC1D40 contactor does not include built-in auxiliary contacts. Auxiliary contacts are added via field-mount LA1D series blocks that clip onto the front or side of the contactor. The most common option is the LA1DN11 (1 NO / 1 NC). Some assembled or pre-kitted variants may ship with an LA1D block already attached — check the individual variant listing. If you need auxiliary contacts, call us at 1-800-222-5129 and we will confirm what is included with the specific part number you are ordering.
What is the difference between LC1D40 and LC1D40A?
In Schneider Electric TeSys D part numbers, the “A” in LC1D40AG7 is part of the catalog number structure for the 40A frame — it indicates the standard 3-pole configuration at this ampere rating. The base model reference “LC1D40” refers to the same 40A contactor family. Full catalog numbers for specific variants always include the frame letter and coil voltage suffix, for example LC1D40AG7 for the 120V AC coil version.
What overload relay is compatible with the LC1D40?
The LC1D40 is compatible with Schneider Electric LRD series thermal (bimetallic) overload relays and LR9D series solid-state electronic overload relays. The overload relay mounts directly to the bottom of the LC1D40 contactor without additional wiring for a compact, integrated motor starter assembly. Select the overload relay range based on your motor’s full-load amperage. Call us at 1-800-222-5129 for overload selection assistance.
What is the difference between TeSys D and TeSys Deca?
TeSys D is the original Schneider Electric IEC contactor line that has been the world’s best-selling contactor family for decades. TeSys Deca is the current updated designation for the same product family — Schneider has progressively rebranded the line under the Deca name. Both TeSys D and TeSys Deca contactors share the same form factor, mounting footprint, and accessory compatibility. LC1D40 units sold today may carry either designation depending on production date and variant.
Which coil voltage should I order for a standard US 120V control circuit?
For a standard US 120V AC control circuit, order the LC1D40AG7 (120V AC coil, 50/60 Hz). The “G7” suffix is the Schneider coil voltage code for 120V AC across the entire TeSys D / Deca range. If your control circuit runs at a different voltage — such as 24V DC (BBE or BD), 240V AC (U7), or 480V AC (T7) — select the corresponding variant from the coil voltage table above or call us at 1-800-222-5129 for ordering assistance.
