What it is and what it does
The Schneider Electric LP1D40004JD is a TeSys Deca 4-pole contactor rated for 60 A in AC-1 (resistive) duty at 440 V, with a 12 V DC coil. It handles motor switching in AC-3 and AC-4 categories as well, making it a general-purpose power contactor for panel builders who need a 4-pole block in a standard rail-plate mount.
Key ratings and what they mean for fit
The 60 A AC-1 rating at 440 V defines its resistive load capacity — heaters, lighting banks, or transformer primaries. For motor loads, the AC-3 category governs switching of 3-phase induction motors. The 4-pole configuration (4P) means all four main poles switch simultaneously, with a non-overlap time of 1.5 ms between NC and NO contacts on both energisation and de-energisation — critical for interlocking reversing starters or bypass circuits where pole overlap could cause a phase-to-phase fault. IP2X finger protection (IEC 60529) means the contactor housing prevents access to live parts with a standard probe — suitable for enclosed panel mounting.
Where it fits in a panel
Mounts on a rail or plate (Mounting support: Rail Plate). Dimensions are 85 mm wide, 127 mm high, 182 mm deep — a standard TeSys Deca footprint that shares the same hole pattern as other LP1D 4-pole blocks. The 182 mm depth is the dimension to watch when spacing the backplate from the enclosure door. Operates at altitudes up to 3000 m without derating, and the TH protective treatment (pollution degree 3) suits it for industrial environments with conductive dust or humidity.
Standards and compliance documentation
Certified to IEC 60947-4-1 (contactors and motor-starters), EN 60947-4-1, BS 5424, VDE 0660, NF C 63-110, and JEM 1038. Flame retardance is V-1 per UL 94; fire resistance tested to 850 °C per IEC 60695-2-1. The manufacturer provides a declaration of conformity covering these standards — request it with the RFQ if your quality documentation requires it.
