The Schneider Electric LP4K1210CW3 is a TeSys K series contactor, 3-pole, rated 12 A in AC-3 utilisation category at ≤440 V. Coil is 36 V DC with a built-in bidirectional peak limiting diode suppressor — no external flyback diode needed on the coil drive. One normally open auxiliary contact is integrated. Flame retardance rated V1 per UL 94, plus compliance with NF F 16-101 and NF F 16-102 Requirement 2.
The AC-3 rating at 12 A governs motor switching — that is the current for starting and disconnecting squirrel-cage motors under full load. The contactor also carries AC-1 (resistive) and AC-4 (plugging/reversing) utilisation categories, so it handles inching or jogging duty within its thermal limits. Hold-in power consumption is 1.8 W at 20 °C, which matters for control transformer sizing and heat buildup in a dense panel.
