The Schneider Electric LP1K12015MD is a TeSys K series contactor, 3-pole, rated 12 A in AC-3/AC-3e utilisation category at 440 V, with a 220 V DC coil and one normally-closed auxiliary contact.
The 12 A AC-3 rating at 440 V governs motor switching — this is the current the contactor can make and break across starting and running conditions for a standard induction motor. The AC-4 rating (72 A at ≤440 V) covers inching and plugging duty, but electrical durability drops sharply to 0.02 Mcycles under that load, so it is not a continuous jogging contactor. Mechanical durability is 10 Mcycles, and maximum operating rate is 3600 cycles per hour, which suits moderate-duty conveyor or pump cycling. The coil holds in at 0.8 to 1.15 Uc and drops out at ≥0.10 Uc, with a 3 W hold-in power draw. Minimum switching capability is 5 mA at 17 V for signalling circuits — useful for PLC-level dry-contact feedback, but verify your load exceeds that threshold to avoid contact oxidation in low-energy circuits. Safety reliability is rated B10d = 1,369,863 cycles under nominal load per EN/ISO 13849-1, and 20,000,000 cycles under mechanical load — relevant if this contactor is used in a safety-related control function.
Certified to EN/IEC 60947-4-1, EN/IEC 60947-5-1, UL 60947-4-1, UL 60947-5-1, CSA C22.2 No 60947-4-1, CSA C22.2 No 60947-5-1, and GB/T 14048.4. Flame retardance meets V1 per UL 94 and Requirement 2 per NF F 16-101/102.
This part is officially obsolete per the manufacturer. If you are holding a legacy panel with this contactor, securing a critical spare before the next failure is the prudent move.
Mounts on printed circuit boards via solder pins (0.035 mm diameter). Dimensions are 58 mm high, 45 mm wide, 57 mm deep. IP2X finger protection. Operating temperature range -25 to 50 °C; storage -50 to 80 °C. No built-in coil suppression — add a free-wheel diode or RC snubber externally per the coil polarity.
