Schneider LC1D40008M7 – TeSys D Contactor

1. Overview:

The LC1D40008M7 is a 4-pole contactor from Schneider Electric’s TeSys D series. It is designed for switching general-purpose electrical loads (AC-1 duty) such as resistive loads, heating elements, and lighting circuits.

This model supports up to 60A at 440V, and uses a 220V AC coil (50/60 Hz) for control operation. It has a 2 NO + 2 NC contact configuration.

2. Key Specifications:

3. Functionality:

• AC-1 Duty Application:
  Designed for non-motor loads such as:

  • Heating circuits

  • Lighting loads

  • Capacitor banks

  • Distribution systems

• 4-Pole Switching:
  Allows switching of three phases plus neutral or use in two separate circuits.

• Versatile Contact Setup (2NO + 2NC):

  • NO (Normally Open): Closes when coil is energized – powers the load.

  • NC (Normally Closed): Opens when coil is energized – often used for interlocking or control logic.

4. Coil and Operation:

• 220V AC Coil:
  Accepts standard mains voltage (single-phase), commonly used in control panels.

• Silent and Efficient:
  The TeSys D series is known for low coil power consumption and mechanical durability.

5. Applications:

• Resistive Load Control (heaters, ovens)

• Lighting Systems

• Power Distribution Switching

• Controlling Neutral + 3 Phase lines

• Automation Panels

• Control Logic Circuits (using NO/NC contacts)

6. Installation & Integration:

• Mounting:
  Compatible with DIN rail or screw mounting.

• Expandable:
  Can be equipped with auxiliary contacts, timers, or mechanical interlocks.

• Compatible with TeSys Accessories:
  Such as overload relays and interface modules.

7. Summary:

The Schneider LC1D40008M7 is a 60A, 4-pole contactor designed for AC-1 applications (non-inductive loads), with a 220V AC control coil. It features 2 NO + 2 NC contacts for flexible wiring in heating, lighting, or distribution systems. Reliable, durable, and part of the modular TeSys D series, it is widely used in industrial and commercial installations.
