Product Description

The Schneider Electric LC1D18G7 is the world’s best-selling 18 A contactor from the legendary TeSys D series — the true “workhorse” size for 7.5 kW / 400 V and 10 HP / 460 V three-phase motors. Still only 45 mm wide with integrated 1 NO + 1 NC auxiliary contacts and 120 VAC coil (G7), it is the default choice for hundreds of millions of motor starters, HVAC units, compressors, and industrial panels globally. Over 100 million TeSys D units sold and counting.

Standard Features

  • Perfect 7.5 kW / 10 HP rating: The most common motor size in industry — one contactor covers virtually every standard 400–480 V application.

  • Same ultra-compact body: Identical 45 mm width and mounting footprint as 9 A / 12 A versions — direct upgrade without redesign.

  • Built-in auxiliaries: 1 NO + 1 NC already included — no add-on block needed for 95 % of starters.

  • 120 VAC coil (G7): The North-American standard — drop-in replacement for Square D 8910DPA, Siemens 3RT20, ABB AF, and legacy Allen-Bradley contactors.

  • Proven for decades: The single most installed contactor model on Earth — spare parts available everywhere, forever.
