Product Features
- Compact 45mm Frame: Standard TeSys D frame width allows for high-density installation in control panels, sharing the same footprint and accessories as the LC1D09, LC1D12, LC1D25, and LC1D32.
- IP20 Finger-Safe Terminals: Touch-safe screw clamp terminals with North American and international terminal markings protect against accidental contact during wiring and maintenance.
- No Built-In Auxiliary Contacts: The base LC1D18 ships without auxiliary contacts. Front-mount LADN series blocks (LADN11, LADN20, LADN02, and mixed configurations) and side-mount LAD8N blocks snap on without tools — select your configuration from the auxiliary contacts dropdown above.
- Versatile Overload Protection: Pairs directly with Schneider LRD series thermal overload relays (LRD01–LRD35, covering 0.10A–38A). For an 18A motor, the LRD21 (12–18A) or LRD22 (16–24A) are the typical choices — select from the overload relay dropdown above.
- High Endurance: Designed for millions of mechanical cycles, suitable for heavy-duty switching in HVAC, pumping, compressor, and conveyor applications.
- Global Certifications: Fully compliant with UL, CSA, IEC, CE, and CCC standards for domestic and international panel builds.

Frequently Asked Questions
What does LC1D18 mean?
The part number follows Schneider Electric’s TeSys D naming convention: LC1 = IEC contactor, D = TeSys D frame size, 18 = 18A AC-3 current rating. The suffix code identifies the coil voltage — for example, LC1D18G7 is the 120V AC version and LC1D18B7 is the 24V AC version. Select your coil voltage from the dropdown above to get the correct full part number added to your order.
What is the difference between the LC1D18 and LC1D09?
The LC1D09 is rated 9A AC-3 (5 HP @ 460V) and the LC1D18 is rated 18A AC-3 (10 HP @ 460V). Both use the same 45mm TeSys D frame, meaning LADN and LAD8N auxiliary contact blocks and LRD overload relays are fully interchangeable between the two. Choose the LC1D18 when your motor’s full-load amps exceed the LC1D09’s 9A rating.
What overload relay pairs with the LC1D18?
The Schneider Electric LRD series thermal overload relays mount directly to the LC1D18 to create a complete motor starter. For most 18A applications, the LRD21 (adjusts 12–18A) or LRD22 (adjusts 16–24A) are the correct choices. Match the LRD range to your motor’s full-load amps (FLA) from the nameplate. All compatible LRD options from LRD01 through LRD35 are available in the overload relay dropdown above.
Does the LC1D18 come with auxiliary contacts?
No — the base LC1D18 ships without auxiliary contacts. Auxiliary contact blocks are field-mountable accessories. Front-mount LADN series blocks (1NO/1NC, 2NO, 2NC, and mixed configurations) and side-mount LAD8N blocks snap on without tools. Select the configuration you need from the auxiliary contacts dropdown above.
What is the LC1D18 a replacement for?
The LC1D18 is the current Schneider Electric replacement for older Telemecanique LC1D18 units and is cross-compatible with existing TeSys D panel assemblies. It is also a functional equivalent to other 18A IEC contactors including the Siemens 3RT2026, Eaton XTCE018, and WEG CWM18 — though mounting footprint and terminal position may vary. Contact us at 1-800-222-5129 to confirm compatibility before ordering for a field replacement.
Is the LC1D18 in stock for same-day shipping?
Yes — the LC1D18 is a stocked item at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship the same business day. Current stock quantity is shown on this page. If you need a specific coil voltage that shows low or no stock, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
