What It Is and What It Does
The Schneider Electric LP1D65004BW is a 4-pole contactor from the TeSys Deca range, rated for resistive loads at 80 A AC-1 at 440 V, with a 24 V DC coil. It's a panel-mount component used to switch power circuits in industrial control cabinets, typically for heater banks, lighting, or other resistive loads where the AC-1 rating governs continuous current.
Key Ratings and What They Mean for Fit
The AC-1 rating of 80 A at 440 V defines its capacity for resistive loads — this is the current it can carry continuously without overheating. For motor duty (AC-3), the contactor is also rated, but the specific current value isn't listed here; the AC-1 figure is the one to match against your load's steady-state draw. The 24 V DC coil means it pulls in cleanly on a standard 24 VDC control supply, with a dropout threshold typically around 18 V. The 4-pole configuration (4P) allows switching of three phases plus neutral, or four independent resistive circuits. The contactor carries approvals under IEC 60947-4-1, EN 60947-4-1, VDE 0660, BS 5424, and NF C 63-110, which cover its use in industrial control panels across Europe and other IEC-adopting regions. Flame retardance is V1 per UL 94, and fire resistance to 850 °C per IEC 60695-2-1, so it meets the thermal runaway containment requirements for enclosed panel installations. Operating temperature range is -40 to 60 °C, with derating above 60 °C up to 70 °C. Storage range extends from -60 to 80 °C. The IP2X degree of protection (per IEC 60529 and VDE 0106) means it's finger-safe but not sealed against moisture — mount it inside a panel with appropriate enclosure rating.
Integration Notes
Mounts on a rail or plate (mounting support: Rail Plate). Dimensions are 85 mm wide, 127 mm high, 182 mm deep — check your panel's DIN-rail spacing and enclosure depth before committing. The 85 mm width is standard for a 4-pole contactor in this frame size, but verify adjacent device clearance for wiring and heat dissipation. The non-overlap time of 1.5 ms between NC and NO contacts on both energisation and de-energisation ensures mechanical interlocking for reversing or star-delta applications.
