Product Description
Schneider Electric LC1D18G7 — TeSys D, 18A AC-3, 120V Coil, 10 HP @ 460V
The Schneider Electric LC1D18G7 is a 3-pole, 18A AC-3 IEC contactor from the TeSys D series with a 120V AC (50/60 Hz) coil (G7 suffix). It is rated at 10 HP at 460V three-phase and includes 1 NO + 1 NC auxiliary contacts built-in as standard. Compatible LRD series overload relays direct-mount to the bottom. The replacement coil for this contactor is the LXD1G7. For other coil voltages, see the LC1D18 coil variant table below. Note: the current-generation equivalent is the LC1D18AG7 (TeSys Deca, EverLink terminals) — both share the same HP ratings and frame dimensions.

Product Features
- TeSys D — Screw Clamp Terminals: The LC1D18G7 belongs to Schneider Electric’s TeSys D series, which uses standard screw clamp power terminals. The current-generation equivalent is the LC1D18AG7 (TeSys Deca), which replaces the screw clamp with EverLink BTR (push-in spring) terminals for tool-free conductor insertion. Both carry the same 18A AC-3 / 10 HP @ 460V rating and use the same auxiliary contact accessories.
- 120V AC Coil — G7 Suffix: The G7 suffix designates a 110V AC (50Hz) / 120V AC (60Hz) coil. This is the most common control voltage for US industrial panels. The replacement coil is the LXD1G7, field-replaceable without removing the contactor from the panel.
- 1 NO + 1 NC Auxiliary Contacts Built-In: The LC1D18G7 includes 1 NO + 1 NC auxiliary contacts as standard. Additional front-mount LADN blocks (LADN11, LADN20, LADN22, etc.) or side-mount LAD8N blocks can be added to expand control circuit capability. All LADN/LAD8N blocks are available as add-on options at checkout.
- LRD Overload Relay Compatible: Schneider Electric LRD series Class 10 overload relays direct-mount to the bottom of the LC1D18G7. The full LRD range (LRD01 through LRD35, covering 0.10–38A) is available as add-on options at checkout. Select the LRD range covering your motor’s nameplate full-load amperage.
- Marine and International Certifications: In addition to UL and CSA, the LC1D18G7 carries Bureau Veritas (BV), RINA, DNV-GL, Lloyd’s Register of Shipping (LROS), and EAC certifications, making it suitable for marine, offshore, and international applications where these classification society approvals are required.
- 15 Million Mechanical Operations: The TeSys D series is rated for 15 million mechanical switching cycles, providing exceptional service life in high-cycle applications such as conveyors, compressors, and repetitive machine operations.

Frequently Asked Questions
Is the LC1D18G7 a TeSys D or TeSys Deca contactor?
The LC1D18G7 is a TeSys D contactor (legacy series, screw clamp terminals). The TeSys Deca equivalent is the LC1D18AG7, which has EverLink BTR (push-in spring) terminals and is Schneider Electric’s current production contactor. Both have the same 18A AC-3 / 10 HP @ 460V rating and accept the same LADN/LAD8N auxiliary blocks and LRD overload relays. The key physical difference is the terminal type: screw clamp (TeSys D) vs. tool-free spring (TeSys Deca).
What does the G7 coil suffix mean on the LC1D18G7?
The G7 suffix designates a 110V AC (50Hz) / 120V AC (60Hz) coil — the most common control voltage in US industrial panels. Other common TeSys D coil suffixes include: B7=24V AC, E7=48V AC, F7=110V AC (note: F7 and G7 are both 120V-range coils but with slightly different characteristics), U7=240V AC, T7=480V AC, and BD=24V DC. The replacement coil for the LC1D18G7 is the LXD1G7.
What overload relay should I use with the LC1D18G7?
The LC1D18G7 is compatible with the full Schneider Electric LRD series Class 10 thermal overload relays, which direct-mount to the bottom of the contactor. Select the LRD range that covers your motor’s nameplate full-load amperage. Common selections for 10 HP motors at 460V (typically 14–17A FLA) are the LRD21 (12–18A) or LRD22 (16–24A). All LRD ranges from LRD01 (0.10–0.16A) through LRD35 (30–38A) are available as add-on options at checkout.
What auxiliary contacts are compatible with the LC1D18G7?
The LC1D18G7 includes 1 NO + 1 NC built-in. Additional auxiliary contact blocks that are compatible include front-mount LADN series blocks (LADN11 for 1NO/1NC, LADN20 for 2NO, LADN22 for 2NO/2NC, LADN40 for 4NO, etc.) and side-mount LAD8N series blocks (LAD8N11, LAD8N20). All are available as add-on options at checkout.
How do I replace the coil on the LC1D18G7?
The TeSys D coil is field-replaceable without removing the contactor from the panel. The replacement coil for the LC1D18G7 (120V AC) is the LXD1G7. The coil module snaps out from the front of the contactor after releasing a retaining tab, and the new coil snaps back in. No tools required for the coil swap itself. If you need a different coil voltage, other LXD1 coil modules are available — call Kent at 1-800-222-5129 to confirm availability.
Does the LC1D18G7 qualify for same-day shipping?
Yes — the LC1D18G7 is in stock at Kent Electrical Supply’s warehouse in Emmaus, PA and ships same business day when ordered before 4:00 PM EST. For LRD overload relays, LADN auxiliary blocks, LXD1G7 replacement coils, or bulk orders, call 1-800-222-5129 or text your RFQ to 484-425-0652.
