The LP2K1201UD3 is a TeSys K reversing contactor, 3P, AC-3 ≤ 440 V 12 A, 250 V DC coil, 1 NC. The 1 NC auxiliary contact is wired into the opposite-direction coil circuit to block simultaneous engagement, a standard safety practice for reversing starters.
AC-3 rating is 12 A at 440 V. AC-4 and AC-1 ratings also apply. IP20 per VDE 0106. The 2000 m altitude rating without derating means it works at most industrial sites; above that, you'd need to factor in air-density effects on arc extinction. Mechanical robustness is specified for shock and vibration per IEC 60068-2-27 and -6 — it holds closed through 15 Gn shocks on the Z axis, and stays open through 10 Gn. That's enough for general industrial machinery but not for extreme off-road or naval applications.
There is no official L* successor listed in the evidence, so a direct drop-in replacement isn't confirmed. If you're designing a new panel or replacing a failed unit, the practical move is to cross-reference the TeSys K family for a current-production reversing contactor with the same coil voltage (250 V DC), pole count (3P), and AC-3 rating (12 A). The physical footprint and mounting pattern of the TeSys K series are consistent, so a newer TeSys K variant is the first place to look. V1 flame retardance per UL 94 and NF F 16-101/102. Protective treatment per IEC 60068 and DIN 50016. IP20 per VDE 0106.
