The LP5K12013BW3 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit preassembled with a reversing power busbar, rated for AC-3 motor duty at 12 A up to 440 V, with a 24 V DC coil and one NC auxiliary contact. It is designed for control applications where a motor must be reversed by swapping two phases, typically in conveyor drives, hoists, or pump stations. The reversing busbar is already integrated, which saves panel wiring time compared to building the interlock externally.
The AC-3 rating of 12 A at ≤440 V governs motor switching — this is the contactor's real-world capacity for starting and stopping a squirrel-cage induction motor under load. AC-1 (resistive) and AC-4 (plugging/inching) utilisation categories are also listed, so the same block can handle heater banks or high-stress reversing duty, but the AC-3 number is the one that decides fit for a standard motor branch circuit. IP20 protection means it is suited for enclosure mounting, not washdown environments. Flame retardance is certified to UL 94 V1 and NF F 16-101/102, which is relevant for rail or public-transit applications where material flammability is specified. Operating altitude is 2000 m without derating, so standard panel installations at most industrial sites are fine.
Mechanical and environmental robustness
The contactor is rated for 15 Gn shock (closed) and 4 Gn vibration (closed) per IEC 60068-2-27 and -2-6, so it holds in on high-vibration machinery like compressors or mobile equipment.
