Telemecanique TeSys D LC1 D25 Contactor (Schneider Electric)

Telemecanique TeSys D LC1 D25 Contactor (Schneider Electric)

Product Description

The LC1 D25 magnetic contactor is a power switching device in the professional TeSys D series. It is designed to control medium-power three-phase electric motors and operate in power distribution circuits. This model features increased contact wear resistance and heavy-duty (AC-3) operation, ensuring reliable starting and stopping of industrial equipment.

Main Technical Parameters

Switching Capabilities (AC-3):

• At 230 V: Power up to 5.5 kW.

• At 400 V: Power up to 11 kW.

• At 500–690 V: Power up to 15 kW.

Electrical Specifications:

• Rated Current (AC-3): 25 Amps.

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

• Control coil voltage: 230 V AC, 50/60 Hz.

• Insulation voltage (U_{i}): 690 V.

• Impulse voltage (U_{imp}): 6 kV.

Contact configuration:

• Power contacts: 3 poles (NO - normally open).

• Built-in auxiliary contacts: 1 NO (normally open) + 1 NC (normally closed).

Installation and connection

Connection parameters:

• Wire used: Copper (CU), AWG 6-14.

• Recommended insulation stripping length: 10 mm.

• Tightening torque for power terminals: 2.3 N⋅m (20 lb.in).

• Tightening torque for auxiliary contacts: 1.7 N⋅m.

Safety and Standards:

The device complies with strict international standards: IEC 947, EN 60947, VDE 0660, and BS 5424. The contactor is suitable for use in networks with short-circuit currents up to 5000 RMS when protected by NTD fuse links.

Model Advantages

• Power and Size Balance: High load capacity (25 A) while maintaining a standard compact housing.

• Efficiency: Low control coil power consumption and low heat dissipation of the power contacts.

• Informative: Clear color indication of tripping on the front panel.

• Easy Scalability: Compatible with the entire TeSys accessory line (thermal relays, time delay modules, auxiliary contact blocks).
