LC1D12 (TeSys D, 12 A)
Schneider / Telemecanique · TeSys D 9–18 A (45 mm)
12 A TeSys Deca — the small-motor workhorse between the LC1D09 and LC1D18, used on dryer fans, small pumps and 3–7.5 HP compressors.

Typical measured coil resistance (±15%, ballpark)
24 VAC (B7)≈ 8–15 Ω
120 VAC (G7)≈ 180–300 Ω
240 VAC (U7)≈ 700–1,300 Ω
480 VAC (V7)≈ 3,000–5,000 Ω
OL = open coil · near zero = shorted turns · coil-to-frame must read >1 MΩ.
Coil resistance checker
Pick the coil voltage, enter your meter reading across A1–A2 (coil disconnected), and compare it to the expected ballpark.
Ω
This model (24 VAC (B7) table value)8 Ω–15 Ω
Generic small-frame 24 VAC8 Ω–16 Ω
OL = open coil. 0–2 Ω = shorted turns (often from a cooked transformer). Ballpark only (±15%+); electronic wide-range coils (e.g. ABB AF) read misleading values — test those at rated voltage instead. Always measure coil-to-frame too: must be >1 MΩ.
Terminals & accessories
Power/coil terminals: Screw clamp 1–6 mm²; coil A1/A2
Auxiliary contacts: 1 NO or 1 NC built in; LADN front blocks add up to 4
Companion overload: LRD thermal (LRD07/08 typical) or LR2K

Field notes
- LADN aux blocks are shared across LC1D09–D38 — a spare block covers the whole small frame range.
- Genuine Schneider coils are marked with the voltage code (G7 = 120 V); counterfeit units often omit it and run hot.
- The LRD overload clips directly beneath — no wiring, but the reset lever must be free of the door for panel-mounted reset.
