Industrial motor control
The Schneider Electric SQUARE D LC1D18T7 is an IEC magnetic contactor rated for 18 A inductive loads at 480 V AC across three poles. It suits panels that switch three-phase motors, heating circuits or lighting banks in commercial and light-industrial installations.
Panel integration
The unit mounts on a standard DIN rail or directly onto a plate, measuring 3.03 in high by 1.77 in wide. Screw-clamp terminals accept control and power conductors without special tools. Two built-in auxiliary contacts (1NO/1NC) provide status feedback or interlock wiring, leaving no need for extra accessory blocks.
Thermal and electrical behaviour
With a 480 V AC coil the contactor draws minimal holding current, and the open-frame design relies on natural convection around the enclosure. Non-reversing operation eliminates the extra winding heat of reversing types. At 5 hp (240 V AC three-phase) the contacts run within their thermal rating during normal duty cycles.

Questions about this item
Will the 18 A inductive rating hold up when the contactor runs continuously at full load?
The contactor is rated for 18 A full-load inductive current per IEC specifications, so sustained operation at that level is within its design limits.
How much heat and noise does the 480 V AC coil produce during all-day operation?
The 480 V AC coil operates silently with no moving parts once energised; heat rise is typical for IEC contactors of this size and is dissipated through the open frame.
My panel uses screw-clamp terminals — will the existing wiring connect directly?
Yes, the contactor uses screw-clamp terminals compatible with standard panel wiring; no special connectors or adapters are required.
