The LP1D40004FW is a 4-pole (4NO) contactor from the TeSys Deca range, rated 60 A in AC-1 utilisation category at 440 V — that's the resistive load rating, so it handles heater banks, lighting, or transformer primaries at that current. The 110 V DC coil means it's for control circuits running on DC voltage, common in battery-backed or industrial DC systems. Terminals are screw-clamp type, which is the standard for panel wiring in most regions. It's also listed for AC-3 and AC-3e duty (motor switching), though the AC-1 figure is the headline rating here. The part carries approvals under VDE 0660, IEC 60947-4-1, EN 60947-4-1, BS 5424, and NF C 63-110, so it's accepted across European and UK installations. Flame retardance is V1 per UL 94, and fire resistance is 850 °C per IEC 60695-2-1.
If you need a drop-in replacement with the same coil voltage and pole count, the closest functional match would be a current-production TeSys Deca contactor with 110 V DC coil and 4 poles — but pinout and mounting dimensions should be cross-checked against the panel layout before committing the BOM line.
Dimensions are 182 mm deep, 85 mm wide, 127 mm tall. Mounting is on a rail or plate — the part accepts both DIN-rail snap-on and panel-mount screw fixing. IP2X finger protection per IEC 60529 means it's safe for open-panel use where accidental contact is a concern.
