Telemecanique LC1 D09 Contactor (Schneider Electric)

Telemecanique TeSys D LC1 D09 Contactor (Schneider Electric)

Product Description

The LC1 D09 low-power three-pole electromagnetic contactor is designed for controlling electric motors and switching resistive loads. It features a compact design and an energy-efficient DC control coil. It is equipped with a bidirectional surge suppressor (LAD4TBDL module), making it ideal for use in circuits with sensitive electronics or PLCs.

Main Technical Parameters

Switching Capabilities (AC-3):

• At 230 V: Power up to 2.2 kW.

• At 400 V: Power up to 4 kW.

• At 500–690 V: Power up to 5.5 kW.

Electrical Specifications:

• Rated Current (AC-3 Mode): 9 Amps.

• Thermal current (I_{th}): 25 Amps (at temperatures up to 40°C).

• Control coil voltage: 24 V DC.

• Insulation voltage (U_i): 690 V.

• Impulse voltage (U_{imp}): 6 kV.

Contact configuration:

• Power contacts: 3 poles (NO).

• Auxiliary contacts: 1 NO (normally open) + 1 NC (normally closed).

Installation and connection

Connection parameters:

• Wire used: Copper (CU), cross-section from 10 to 18 AWG.

• Recommended insulation strip length: approximately 8 mm (5/16").

• Power terminal tightening torque: 1.7 N⋅m (15 lb.in).

• Auxiliary terminal and coil tightening torque: 1.7 N⋅m.

Safety and Standards:

The contactor is certified to IEC/EN 60947, VDE 0660, and JIS C8201-4-1. The device features built-in coil protection (LAD4TBDL) operating in the 5–24 V range, preventing backsurge voltage during disconnection.

Model Advantages

• Safe operation with PLCs: The 24 V DC coil allows the contactor to be connected directly to controller outputs without intermediate relays.

• Interference protection: Includes a surge suppression module.

• Compact size: Small dimensions save space in the electrical panel.

• Visual inspection: Transparent cover on the front panel for quick identification condition and markings.

Country of origin: France.
