Product Name:

Schneider LC1D09BD – TeSys D Contactor

1. Overview:

The Schneider LC1D09BD is a 3-pole contactor from the TeSys D series, designed for controlling AC motors and power circuits. It’s compact, reliable, and widely used in industrial and commercial motor control panels.

This model is rated for 9A (AC-3 duty), and operates with a 24V DC coil, making it suitable for low-voltage control systems.

2. Key Specifications:

3. Functionality:

• Motor Control (AC-3 duty):
  Designed to switch 3-phase squirrel cage motors during running (not starting).

• Remote Switching:
  Can be controlled from a push button, PLC output, or automation system using the 24V DC coil.

• Load Isolation:
  Disconnects motors or loads during maintenance or when not in use.

4. Coil and Operation:

• 24V DC Coil:
  Operates silently and efficiently. Ideal for control systems powered by 24VDC (common in panels with PLCs).

• Fast Response:
  DC coils in TeSys D contactors have built-in surge suppressors, reducing electrical noise and increasing lifespan.

5. Applications:

• Industrial Machines

• HVAC Systems

• Pumps, Fans, Compressors

• Automated Control Panels

• Motor Starters (used with overload relays)

6. Mounting & Compatibility:

• DIN Rail or Panel Mounting:
  Easy installation in standard control enclosures.

• Auxiliary Contact Blocks Available:
  Can be extended with additional NO/NC contacts for control signaling.

• Works with Overload Relays:
  Typically paired with TeSys LR2D overload relays for full motor protection.

7. Summary:

The Schneider LC1D09BD is a 3-pole contactor, rated 9A (AC-3), with a 24V DC control coil. It’s ideal for switching 3-phase motors up to around 4kW, offering high reliability, compact size, and easy integration into control panels or automation systems.
