What it is and what it does
The Schneider Electric LP1D65004EW is a 4-pole contactor from the TeSys Deca range, rated for AC-1 resistive loads at 440 V and 80 A. The coil is 48 VDC. It is designed for plate or rail mounting in control panels. The AC-1 rating (80 A at 440 V) covers resistive heating and lighting loads. The contactor also carries AC-3 and AC-4 utilisation categories, meaning it can switch squirrel-cage motors and inching/plugging duty, though the motor current rating will be lower than the AC-1 figure — check the motor full-load amps against the AC-3 rating for the specific voltage. The non-overlap time between NC and NO contacts is 1.5 ms on both energisation and de-energisation.
Sourcing and lifecycle reality
This obsolete TeSys Deca part may not have a direct drop-in replacement from the current TeSys range. Verify footprint, coil voltage, and terminal layout before ordering.
Standards and environmental ratings
The LP1D65004EW complies with IEC 60947-4-1 and EN 60947-4-1, the core standards for contactors and motor-starters. It also meets VDE 0660, JEM 1038, and BS 5424. The IP degree of protection is IP2X per IEC 60529 and VDE 0106 — finger-safe but not sealed against moisture or dust. The contactor is rated for operation up to 3000 m altitude without derating, and the permissible ambient temperature range is -40 to 60 °C (with derating up to 70 °C). Storage range is -60 to 80 °C. The protective treatment is TH (pollution degree 3) per IEC 60068, suitable for industrial environments with conductive pollution. Fire resistance is rated at 850 °C per IEC 60695-2-1, and the flame retardance is V1 per UL 94. Mechanical robustness is specified for shocks (10 Gn open, 15 Gn closed) and vibrations (2 Gn, 5-300 Hz open; 4 Gn, 5-300 Hz closed).
