What this contactor is and what the ratings mean
The Schneider Electric LP1D65004MD is a 4-pole contactor from the TeSys Deca range, rated AC-1 80 A at 440 V for resistive loads, with a 220 V DC coil. That AC-1 rating is the continuous current it can carry in resistive heating or lighting circuits — the real-world number for sizing, not a peak. For motor duty, it also carries AC-3 and AC-4 utilisation categories, so it handles squirrel-cage motors up to its rated switching capacity without welding contacts on start-up. Non-overlap time between NC and NO contacts is 1.5 ms on both energisation and de-energisation — that matters if you're interlocking two contactors for reversing or star-delta transitions; the delay prevents a momentary short across the poles.
Where it goes and what it connects to
Mounts on a rail or plate — the 85 mm width and 127 mm height fit a standard TeSys Deca footprint, so it swaps into an existing panel layout without re-drilling. IP2X finger protection means the live terminals are shielded from accidental contact inside an enclosure, which is the minimum for a panel-mounted contactor behind a locked door.
Standards and compliance
Compliant with IEC 60947-4-1 (the main contactor standard), EN 60947-1, VDE 0660, BS 5424, NF C 63-110, and JEM 1038. Fire resistance rated to 850 °C per IEC 60695-2-1, and the housing carries a V-1 flame retardance rating per UL 94. Protective treatment is TH (pollution degree 3) per IEC 60068, so it's suitable for industrial environments with conductive dust or moderate condensation.
