Schneider LC1D0910 Contactor (TeSys D Magnetic Contactor)

 

4

The Schneider LC1D0910 is a TeSys D three-pole magnetic contactor, designed for motor starting and power switching in industrial automation and electrical distribution systems.

Product Information

• Brand: Schneider Electric
• Series: TeSys D
• Model: LC1D0910
• Type: AC Magnetic Contactor
• Main Contacts: 3 NO (3-pole)
• Auxiliary Contacts: 1 NO (built-in)
• Rated Operational Current (AC-3): 9 A (up to 440 V)
• Rated Insulation Voltage (Ui): 690 V
• Mounting: DIN rail or panel mounting
• Coil Voltage: Depends on the suffix code (e.g., G7 = 120 VAC, P7 = 230 VAC, B7 = 24 VAC). The base model LC1D0910 alone does not specify the coil voltage.

What it actually is

This is not a relay module and not a PLC module.

It is an electromagnetic contactor used to:

• Start and stop three-phase motors
• Switch industrial power circuits
• Control pumps, fans, compressors, and conveyors
• Interface with PLCs, push buttons, and control relays

System Role (Simple)

PLC / Push Button / Relay

→ LC1D0910 Contactor

→ Three-phase Motor or Industrial Load

The contactor uses an electromagnetic coil to open and close the main power contacts.

Key Features

• 3-pole power contacts
• Built-in 1 NO auxiliary contact
• AC-3 rating of 9 A
• Compact TeSys D design
• DIN rail or panel mounting
• Long mechanical and electrical service life
• Wide range of compatible accessories (auxiliary contacts, timers, interlocks, suppressors)

Typical Applications

• Motor control centers (MCC)
• Conveyor systems
• Pumps and compressors
• HVAC equipment
• Industrial machinery
• Factory automation
• Power distribution control panels

Advantages

• Reliable motor switching performance
• Compact installation footprint
• Easy maintenance and replacement
• Extensive Schneider TeSys accessory compatibility
• Suitable for frequent switching applications

Important Notes

• Not a PLC ❌
• Not a relay module ❌
• Not a circuit breaker ❌
• It is an electromagnetic motor contactor ✔
• The coil voltage cannot be determined from "LC1D0910" alone. You need the complete part number (such as LC1D0910G7, LC1D0910P7, etc.) to identify the coil voltage.

Precautions

• Verify the coil voltage suffix before installation.
• Select the contactor according to the motor's AC-3 current.
• Tighten terminals to the recommended torque.
• Use an overload relay (such as the TeSys LRD series) for motor protection.
• Install in a clean, dry electrical enclosure.
