Schneider Electric Telemecanique LC1D40004 Contactor

The Schneider Electric Telemecanique LC1D40004 is a four-pole IEC magnetic contactor in the TeSys D family, designed for industrial power switching and resistive load control. It provides up to 60 A (AC-1) with four main normally-open contacts and one normally-open plus one normally-closed auxiliary contact (mechanically linked). The device accepts a control coil voltage that is coil-code dependent and supports Ue up to 690 V AC (25–400 Hz) and up to 300 V DC on the power circuit, with utilization categories AC-1, AC-3, AC-3e, and AC-4. Insulation voltage Ui is 690 V, and the unit offers a Uimp of 6 kV, Ith of 60 A, and IP20 protection, with screw-clamp terminals. Mounting is compatible with DIN rail or panel mounting. It complies with IEC 60947-4-1 and is UL Listed, CSA Certified, CE Marked. Common applications include industrial heating equipment, lighting control panels, HVAC systems, power distribution panels, and process automation; it is also used in automation systems requiring reliable four-pole switching. Common replacements include Schneider Electric LC1DT60 4-Pole TeSys Deca Contactor, Siemens SIRIUS 3RT20 4-Pole Contactor, and Allen-Bradley Bulletin 100-C IEC 4-Pole Contactor.
