Schneider Electric TeSys D Contactor LC1D50A | 3-Pole (3NO), AC-3 50A, <= 440V, Coil EverLink Motor Control Switch

Schneider Electric TeSys D 3-Pole Automatic Contactor (Model: LC1D50A) is an industrial-grade, heavy-duty magnetic switching switchgear engineered to deliver premium operational control over heavy electric motors, commercial HVAC ventilation arrays, and severe inductive loads. Fully optimized for high-stress $AC-3$ utilization categories, this high-performance contactor manages a continuous operational current of 50A for motors up to 440V AC, providing the precise electrical calibration required to run standard 22 kW (30 HP) to 30 kW (40 HP) 3-phase induction motors at 380V/400V.

Belonging to Schneider Electric’s world-renowned TeSys D flagship range, the LC1D50AM7 features a robust 55mm frame size equipped with patented EverLink terminal blocks. This technology ensures permanent tightening pressure on power cables, completely eliminating the risk of wire arcing due to cable creepage or continuous physical panel vibrations. Built with an integrated 50/60Hz activation coil, this 3-Pole contactor features a 3NO (3 Normally Open) main power pole architecture coupled with built-in auxiliary contacts (1NO + 1NC) as standard to facilitate immediate electrical interlocking, safety feedback loops, 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 environment 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 industrial water pumps, exhaust fan arrays, large conveyor lines, and commercial elevator panels across Egypt.

Key Technical Features:

• 50A 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 80A (at <= 60°C) for non-inductive resistive applications like industrial heating blocks and large lighting arrays.

• Integrated Coil: Calibrated perfectly to operate natively on the standard Egyptian building control grid without requiring reduction control transformers.

• Patented EverLink Technology: Advanced terminal block separations ensure constant cable tightening pressure, eliminating local hot-spots and connection failures.

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