Schneider Electric TeSys D Contactor LC1D80A | 3-Pole (3NO), AC-3 66A/80A, <= 440V Heavy-Duty Industrial Motor Control Switch

Schneider Electric TeSys D 3-Pole Automatic Contactor (Model: LC1D80A) is an industrial-grade, heavy-duty magnetic switching device engineered to deliver premium operational control over large electric motors, commercial HVAC ventilation arrays, and severe inductive loads. Optimized for high-stress $AC-3$ utilization categories, this high-performance contactor manages a continuous operational current of 66A to 80A for motors up to 440V AC, providing the precise electrical calibration required to run standard 37 kW (50 HP) to 45 kW (60 HP) 3-phase induction motors at 380V/400V.

Belonging to Schneider Electric’s world-renowned TeSys D flagship range, the LC1D80A features a robust 85mm frame size built with high-integrity terminal clamp connections designed to prevent loose wire arcs caused by continuous mechanical site vibrations. Built with a high-integrity 3NO (3 Normally Open) main power pole architecture, the LC1D80A includes integrated auxiliary contacts (1NO + 1NC) as standard to facilitate immediate electrical interlocking, remote status feedback, or automated PLC control logic. Engineered with advanced arc-chute grids and high-grade silver-nickel alloy contact tips, it withstands demanding high-frequency duty cycles under harsh, high-temperature environmental parameters. Fully compliant with international safety benchmarks including IEC/EN 60947-4-1, this premium block mounts easily onto standard DIN rails or mounting plates, establishing itself as the definitive professional choice for heavy industrial water pumps, exhaust fan arrays, large conveyor lines, and commercial elevator panels across Egypt.

Note: The complete structural part number varies depending on your required control circuit voltage coil (e.g., LC1D80AM7 for 220V AC, LC1D80AP7 for 230V AC, LC1D80AB7 for 24V AC, or LC1D80ABD for 24V DC).

Key Technical Features:

• 80A Continuous Operational Current (AC-3): Precision-calibrated for continuous-duty starting, reversing, and stopping of heavy 3-phase induction motors up to 440V.

• AC-1 Resistive Load Rating: Capable of handling a massive 125A (at <= 60°C) for non-inductive resistive applications like large industrial heating blocks and heavy lighting arrays.

• Heavy-Duty 85mm Frame Size: Enhanced structural architecture designed for optimum heat dissipation and maximum electrical endurance under heavy loads.

• Built-in Auxiliary Contacts: Features integrated 1NO + 1NC auxiliary links for seamless electrical interlocking, safety feedback loops, and automation telemetry.

• Robust Multi-Standard Box Lugs: High-torque clamping terminals ensure consistent, robust clamping, fully eliminating dangerous local hot-spots and cable overheating.
