Schneider Electric LC1D18 Motor Starter Assembly

The Schneider Electric LC1D18 Motor Starter Assembly is a preassembled magnetic motor control unit that combines an 18 A AC-3 contactor with a 48 VAC coil and a TeSys LRD thermal overload relay (adjustable 12–18 A). This three‑pole assembly provides manual and remote motor control with integrated overload protection, suitable for IEC motor control applications in pumps, conveyors, compressors, fans, HVAC equipment, and manufacturing machinery. Its TeSys D LC1D18‑series contactor paired with the TeSys LRD overload relay supports operation up to 690 VAC (50/60 Hz), with IP20 protection and screw‑clamp terminals for secure wiring, and mounting on DIN rail or panel. The auxiliary circuit includes 1 NO and 1 NC contact; the device offers thermal overload protection and phase failure protection with a Class 10A tripping class and a reset that can be manual or automatic. Rated up to 10 HP at 460 VAC, it is CE, UL Listed, and CSA Certified, conforming to IEC/EN 60947-4-1, UL 60947-4-1, and CSA C22.2 standards. Common replacements include Schneider Electric LC1D18E7 + LRD21 Assembly and LE1D18E7, or Eaton PKZM0 + DILM17 + ZB32-18 assemblies.
