New Original Schneider LC1D50AF7C TeSys Deca Electromagnetic Contactor

1. Product Overview

LC1D50AF7C is an authentic original 3-pole AC electromagnetic contactor manufactured by Schneider Electric, categorized under the classic TeSys Deca LC1D series. This model is equipped with an 110V AC control coil and features a rated operational current of 50A under AC-3 utilization category. It serves as a core switching component widely used to control the start, stop and forward-reverse rotation of three-phase asynchronous motors, as well as the on-off switching of inductive and resistive AC loads in machine tools, water pump stations, HVAC ventilation equipment, automated assembly lines, packaging machinery and general industrial low-voltage control cabinets.
The contactor is configured with three main normally open power contacts and fixed built-in 1NO + 1NC auxiliary contacts for signal transmission. When powered by a 400V AC three-phase grid, it can drive three-phase motors with a maximum rated power of 22kW. The AC coil adopts optimized electromagnetic design with low noise during operation and strong anti-vibration performance. It supports two standard installation methods: 35mm DIN rail mounting and direct panel screw fastening. Users can flexibly assemble thermal overload relays, auxiliary contact blocks, mechanical interlock modules, time delay attachments and other TeSys series accessories together with this contactor to build complete motor starter systems with overload protection, electrical interlock and running status monitoring functions. Complying with multiple international electrical safety and environmental standards, it delivers stable long-term performance for frequent switching industrial scenarios.

2. Main Functions

  1. Remote Automatic On/Off Control for Motors and AC Loads

    Applying 110V AC voltage to the built-in coil generates electromagnetic suction to close the main power contacts and energize downstream loads or motors. Cutting off the coil power supply triggers the internal reset spring to separate contacts and disconnect the main circuit. This mechanism realizes remote unattended start-stop control of three-phase motors and switching management of heating pipes, fans, lighting fixtures and other electrical equipment.

  2. Synchronous Working Status Feedback via Auxiliary Contacts

    The integrated one normally open and one normally closed auxiliary contacts act synchronously with the main contacts. They transmit contactor pull-in or release signals to PLC systems, indicator lamps and interlock circuits, which facilitates equipment running monitoring and logic interlock control within the whole automation loop.

  3. Arc Extinguishing Protection for Power Contacts

    Each pole is fitted with an independent sealed arc extinguishing chamber. It rapidly cools, decomposes and eliminates electric arcs generated during contact separation, effectively avoiding arc ablation, contact welding and wear of silver alloy contact tips, greatly extending the service life under frequent switching cycles.

  4. Diversified Function Expansion with Optional Accessories

    Additional functional modules can be installed on the top and side positions of the contactor, including extra auxiliary contact units, mechanical interlock devices for forward-reverse motor control, time delay modules and surge absorption components, to meet diversified customized control demands.

  5. Low Noise & Stable AC Coil Operation

    The AC coil is equipped with shading coils to eliminate electromagnetic vibration noise, ensuring quiet and reliable operation even under continuous working conditions in production workshops.

  6. Finger-Safe Indoor Protection Design

    IP20 protection level prevents maintenance personnel from accidentally touching internal live conductive parts inside electrical cabinets, meeting global industrial electrical safety specifications.
