The LP2K0901JD is a TeSys K reversing contactor — a 3-pole unit rated for 9 A in AC-3 and AC-3e duty at voltages up to 440 V, with a 12 V DC coil and one normally-closed auxiliary contact. It ships preassembled with the reversing power busbar, which saves panel-build time on motor-reversing circuits. The utilisation categories cover AC-1 (resistive), AC-3 (squirrel-cage motor starting), AC-3e (high-efficiency motors), and AC-4 (plugging/inching), so it handles both standard and demanding motor control applications. IP20 finger-safe terminals are standard per VDE 0106.
The 9 A AC-3 rating at ≤440 V is the headline number for motor switching — it tells you this contactor can start and stop a 3-phase induction motor drawing up to 9 A under full-load conditions. The AC-3e category extends that to premium-efficiency motors, which draw slightly higher inrush. The 12 V DC coil is a specific control voltage; verify your PLC or relay output matches before specifying. The 1 NC auxiliary gives you one normally-closed feedback contact for status monitoring or interlocking. Mechanical robustness specs (15 Gn shocks contactor closed, 4 Gn vibration on Z axis) mean it holds in on high-vibration machinery like conveyors or compressors.
The contactor measures 2.3 in high × 3.5 in wide × 2.2 in deep (58 × 90 × 57 mm). The preassembled reversing busbar means the mechanical interlock and power wiring between the two contactors are already in place — you land the line and load connections and wire the coil. Operating altitude is 2000 m without derating; above that, reduce the rated current per IEC 60947.
