LC1D40G7 vs. LC1D40AG7 — What Is the Difference?
The LC1D40G7 and LC1D40AG7 are both 40A, 3-pole, 120V AC coil contactors from Schneider Electric. They are functionally equivalent in rating, auxiliary contacts, and mounting footprint. The key difference is the power circuit terminal design:
| Feature | LC1D40G7 (TeSys D) | LC1D40AG7 (TeSys Deca) |
|---|---|---|
| Power Terminals | Standard screw clamp | EverLink BTR screw connectors |
| Control Terminals | Screw clamp | Screw clamp |
| Current Rating | 40A AC-3 | 40A AC-3 |
| HP @ 480V | 30 HP | 30 HP |
| Coil Voltage | 120V AC, 50/60 Hz | 120V AC, 60 Hz |
| Aux Contacts | 1 NO + 1 NC | 1 NO + 1 NC |
| Footprint | 55mm wide | 55mm wide |
| Status | Legacy / still stocked | Current production |
EverLink BTR is Schneider Electric’s self-tightening spring-loaded screw connector technology that maintains constant clamping force over time, reducing the risk of connection loosening due to thermal cycling. It is standard on the current TeSys Deca (LC1D40AG7) but is not present on the legacy TeSys D (LC1D40G7). If your application or panel specification requires EverLink terminals, order the LC1D40AG7.
HP Ratings by Voltage

| 240V AC | 10 HP | Three-phase |
| 480V AC | 30 HP | Three-phase |
| 600V AC | 30 HP | Three-phase |
LC1D40 Coil Voltage Variants
| Part Number | Coil Voltage | Coil Type |

| LC1D40E7 | 48V AC, 50/60 Hz | AC |
| LC1D40F7 | 110V AC, 50/60 Hz | AC |
| LC1D40G7 (this item) | 120V AC, 50/60 Hz | AC — Most Common US |

Product Features
- 30 HP at 480V: The LC1D40G7 is rated for 30 HP at 480V three-phase (40A AC-3). It is suitable for motor starters in pumping, HVAC, conveyor, compressor, and general industrial applications. Note: some older distributor listings cite 20 HP — this is incorrect. Schneider Electric’s own catalog confirms 30 HP at 480V.
- 1 NO + 1 NC Built-In Auxiliary Contacts: The LC1D40G7 includes both a normally open (NO) and a normally closed (NC) auxiliary contact as standard. The NC mirror contact is IEC certified. Additional front-mount or top-mount LA1D auxiliary contact blocks can be added for expanded control wiring.
- Screw Clamp Terminals, Power and Control: The LC1D40G7 uses standard screw clamp connections on both power and control circuits. If EverLink BTR self-tightening spring connectors are required by your panel specification, order the current-generation LC1D40AG7 (TeSys Deca).
- 120V AC Coil — G7 Suffix: The G7 suffix designates a 120V AC coil rated for both 50 Hz and 60 Hz operation, making this the most common variant for US industrial control panels. The coil operates between 110V AC (50 Hz) and 120V AC (60 Hz).
- TeSys D / TeSys Deca Family: The LC1D40G7 is part of Schneider Electric’s TeSys D contactor series, the predecessor to the current TeSys Deca line. TeSys D contactors remain in production and stock. Accessories, overload relays, and auxiliary blocks are shared across TeSys D and TeSys Deca for this frame size.
- LRD and LR9D Overload Relay Compatible: The LC1D40G7 pairs directly with Schneider Electric LRD series thermal overload relays or LR9D series electronic overload relays for complete motor starter assemblies. The overload relay mounts directly to the load-side terminals (T1-T2-T3) without additional wiring.
- 100 kA SCCR: When used with a coordinated 480V circuit breaker (up to 110A) or a 600V Class J or CC fuse (up to 90A), the LC1D40G7 achieves a Short Circuit Current Rating (SCCR) of 100 kA — suitable for high-fault-current industrial environments.
- DIN Rail or Panel Mount: Mounts on standard 35mm DIN rail or directly to a panel backplate via two screw holes. IP2X (IP20) finger-safe terminal protection standard.

Frequently Asked Questions
What is the HP rating of the LC1D40G7?
The LC1D40G7 is rated 30 HP at 480V three-phase (40A AC-3). It is also rated 30 HP at 600V, 10 HP at 240V, and 10 HP at 200–208V. Some older distributor listings incorrectly show 20 HP — the correct rating per Schneider Electric’s own catalog is 30 HP at 480V.
What is the difference between the LC1D40G7 and the LC1D40AG7?
Both are 40A, 3-pole, 120V AC coil contactors with 1 NO + 1 NC built-in auxiliary contacts. The key difference is the power terminal design. The LC1D40G7 (TeSys D) uses standard screw clamp power terminals. The LC1D40AG7 (TeSys Deca) uses EverLink BTR spring-loaded self-tightening screw connectors on the power circuit, which maintain consistent clamping force over time. Both are electrically equivalent in rating. The LC1D40AG7 is the current production version; the LC1D40G7 is the legacy TeSys D variant. Accessories and overload relays are shared.
Does the LC1D40G7 include auxiliary contacts?
Yes — the LC1D40G7 includes 1 Normally Open (NO) + 1 Normally Closed (NC) built-in auxiliary contacts as standard. The NC mirror contact is IEC certified. Additional auxiliary contacts can be added via LA1D front-mount or top-mount auxiliary contact blocks for expanded control and interlocking requirements.
What overload relay pairs with the LC1D40G7?
The LC1D40G7 is compatible with Schneider Electric LRD series thermal overload relays (Class 10 and Class 20) and LR9D series electronic overload relays. For a 30 HP / 40A application at 480V, select an LRD overload relay sized to your motor’s full-load amperage. The overload relay mounts directly to the T1-T2-T3 load terminals of the contactor. Call Kent Electrical Supply at 1-800-222-5129 for overload selection assistance.
Is the LC1D40G7 the same as the Square D LC1D40G7 or Telemecanique LC1D40G7?
Yes — Schneider Electric, Square D, and Telemecanique all refer to the same product. Schneider Electric acquired Telemecanique in 1988 and Square D in 1991. The LC1D contactor line was originally a Telemecanique product and was subsequently marketed under the Square D brand in North America. The catalog number LC1D40G7 is identical across all three brand references.
Does the LC1D40G7 qualify for same-day shipping?
Yes — the LC1D40G7 is a stocked item at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship same business day.
