What This Part Is and Where It Fits
The Schneider Electric LP1D40004BW is a TeSys Deca 4-pole contactor rated for 60 A in AC-1 resistive load duty at 440 V, with a 24 V DC coil. It's a panel-mount or plate-mount part (182 mm deep, 85 mm wide, 127 mm tall) built for switching resistive loads in industrial control cabinets. The IP2X finger-safe front cover meets IEC 60529 and VDE 0106, so it's acceptable for open-panel installations where accidental contact is a concern.
What the Ratings Mean for Your Decision
The AC-1 rating of 60 A at 440 V governs resistive loads — heaters, lighting banks, non-inductive circuits. That's the number that decides fit for a resistive switching job, not a higher AC-3 motor rating. The 24 V DC coil is common in PLC-driven panels and safety circuits; verify your control supply can deliver the inrush without droop. The contactor carries IEC 60947-4-1 certification for contactors and starters, plus JEM 1038, BS 5424, and VDE 0660 — accepted across European and Asian markets. The TH treatment (pollution degree 3) per IEC 60068 means it's rated for industrial environments with conductive dust and humidity, not clean-room or sealed-panel duty.
Mechanical and Environmental Limits
Operating temperature spans -40 to 60 °C, with derating required above 60 °C up to 70 °C. Storage range is wider at -60 to 80 °C. The contactor withstands 10 Gn shocks when open, 15 Gn when closed, and 2 Gn vibration (5–300 Hz) open, 4 Gn closed — robust enough for most industrial machinery but not extreme mobile equipment. Fire resistance at 850 °C per IEC 60695-2-1 and UL 94 V1 flame retardance on materials. Altitude rating is 3000 m without derating, which covers most installations outside high-mountain sites.
