The LP4K06103FW3 is a 3-pole contactor from Schneider Electric's TeSys K series, rated for AC-3 and AC-4 utilization categories. The built-in bidirectional peak limiting diode suppressor handles the coil's inductive kickback, so you don't need to add an external flyback diode across the coil terminals. The 6 A rating at 10 MOhm for the signalling circuit is for the auxiliary contact, not the main poles.
The coil draws 1.8 W inrush and 1.8 W hold-in at 20 °C — it's a DC-operated contactor with a sealed hold characteristic, so the power consumption stays flat once picked. The built-in diode suppressor means the coil circuit is polarity-sensitive; wire it correctly or the diode won't clamp the back-EMF. The 110 V DC coil is common in battery-backed control systems or DC distribution panels. The contactor's 3 NO main poles and 1 NO auxiliary contact (signalling circuit) give you one set of feedback contacts for PLC status monitoring.
No unusual obsolescence risk on this TeSys K variant.
