What this contactor is and what it does
The Schneider Electric LP1D65004ED is a 4-pole contactor from the TeSys Deca range, rated for 80 A in AC-1 duty at 440 V, with a 48 V DC coil. It's built for switching resistive loads, but also covers AC-3 and AC-4 motor duty categories per IEC 60947-4-1 — so it can handle motor starting and inching as well, not just heaters or lighting.
Key ratings and what they mean for fit
The AC-1 rating of 80 A at 440 V tells you the continuous resistive current it can carry without overheating. For motor loads, you'll need to derate to the AC-3 or AC-4 values — the part's own utilisation category list includes those, but the exact AC-3 current isn't stated here. The 48 V DC coil is a specific control voltage; if your panel runs 24 V DC or 110 V AC, this coil won't pull in. The non-overlap time of 1.5 ms between NC and NO contacts on both energisation and de-energisation means it's safe for reversing or star-delta circuits where you need a guaranteed break-before-make.
Where it fits in the panel
Mounts on plate or rail, with dimensions 85 mm wide, 127 mm high, 182 mm deep. IP2X finger protection means it's safe for open panel mounting but not for washdown environments. Operating temperature from -40 to 60 °C (with derating up to 70 °C) covers most indoor industrial enclosures, and it runs without derating up to 3000 m altitude.
