The Schneider LP1D80004EW is a 4-pole, 4 NO contactor from the TeSys Deca range, rated for resistive loads in AC-1 utilisation category. It handles 80-150 A continuous current and is built for panel-mount applications where you need to switch heater banks, lighting, or other non-inductive loads. The DC wide-range coil (no built-in suppressor) means you supply your own flyback diode or RC snubber — plan for that on the control wiring.
AC-1 rating is the key: this contactor is not rated for motor starting (AC-3) or inductive loads. The 80-150 A range covers resistive circuits like electric heat, lighting contactor banks, or power-factor correction capacitor switching. The 4-pole 4 NO configuration gives you four normally-open power poles — no auxiliary contacts built in, so you'll add a side-mount block if you need feedback to a PLC. Mechanical durability is 4 million cycles; electrical durability is 0.8 million cycles at 125 A AC-1 under 440 V. That's a solid lifespan for a heater-bank contactor that cycles maybe a few times per day. The rated breaking and making capacity is 1100 A at 440 V — enough to handle inrush from cold resistive loads without welding the contacts. Mounting is on a rail or plate (not DIN-rail snap-on — this is a bolt-down Deca frame). Depth is 7.1 in (181 mm), so allow that clearance behind the panel door. Power terminals accept up to 50 mm² cable; torque to 12 N·m. Control circuit terminals are screw clamp, 1-4 mm², torque 1.2 N·m.
