The Schneider LP1D65008DW is a TeSys D 4-pole contactor with a 2 NO + 2 NC pole configuration, rated for AC-1 resistive loads up to 80 A at 440 V. That AC-1 rating means it's designed for switching resistive heater banks, lighting, or transformer primaries where inrush is low — not motor starting (that would be AC-3). The DC wide-range control coil includes a built-in bidirectional peak limiting diode suppressor, so you don't need to add external flyback suppression on the control side.
The 80 A AC-1 thermal current (Ith) at 50 Hz gives the continuous current-carrying capacity of the power circuit — use this for sizing the main conductors and the upstream fuse (associated fuse rating is 125 A gG for type 2 coordination). The rated breaking and making capacity is 1000 A at 440 V, so it can interrupt a fault or close into a shorted load within its coordination limits. Mechanical durability is 6 million cycles; electrical durability is 1.4 million cycles at 80 A AC-1 under 440 V — that's a solid lifespan for a resistive-load machine.
The footprint is 5 in (127 mm) high, 3.3 in (85 mm) wide, and 7.2 in (182 mm) deep — that depth matters when you're laying out a shallow enclosure; check the door clearance if the contactor is mounted near the hinge side. Control circuit terminals take up to 4 mm², torqued to 1.7 N·m.
