The Schneider Electric LP1K1210ED is a 3-pole contactor from the TeSys K series, rated 12 A in AC-3/AC-3e duty at 440 V, with a 48 V DC coil and one normally open auxiliary contact.
The AC-3e rating (12 A) extends this to energy-efficient motors with higher inrush. For resistive loads (AC-1), the contactor handles 20 A. The mechanical durability of 10 Mcycles and electrical durability of 1.3 Mcycles at AC-3 mean this contactor is built for moderate-cycle applications like conveyors or pumps, not high-speed indexing. The 48 V DC coil draws 3 W inrush and hold-in power at 20 °C, with an operating range of 0.8 to 1.15 times the control voltage (Uc). Drop-out occurs at ≥ 0.10 Uc below 50 °C — important for control circuit design where undervoltage release is needed. The coil has no built-in suppressor module, so an external flyback diode or RC snubber should be added to protect the DC control circuit. The contactor carries a B10d of 1,369,863 cycles at nominal load per EN/ISO 13849-1, making it suitable for safety-related circuits where the contactor is part of a monitored safety function. The minimum switching capability of 5 mA at 17 V ensures reliable signalling even with low-energy control signals.
Sourcing Reality: Obsolete Part
This part is classified as obsolete by the manufacturer. For a BOM line or installed base that requires this exact code, sourcing is through surplus or broker channels.
Integration Notes
Tightening torque is 0.8 to 1.3 N·m. IP2X protection means it is not suitable for washdown or outdoor use without an enclosure.
