Rated AC-3 12 A at 440 V, it handles a 3-phase motor up to that switching duty; the 72 V DC coil pulls in reliably on a standard control supply. IP20 finger-safe terminals (VDE 0106) mean it's protected against accidental contact in an enclosure.

Frequently asked questions
What is the closest alternative to LP5K12105SW3 in the TeSys family?
The manufacturer does not list a direct drop-in successor for this obsolete code. A current TeSys K or TeSys D reversing contactor with a 72 V DC coil and 12 A AC-3 rating would be the functional equivalent, but pinout and busbar arrangement must be verified against your panel layout.
What are the key ratings for LP5K12105SW3?
It is a 3-pole reversing contactor rated AC-3 12 A at 440 V, with a 72 V DC coil. The power circuit is rated for 690 V AC 50/60 Hz. IP20 protection, UL 94 V1 flame retardance, and dimensions of 90×58×57 mm.
