The LX1LC042: Coil resistance measures 5.558 Ohm ±10 %, and the closed-circuit inductance is 0.107 mH. Power consumption sits at 12…18 VA sealed (holding), but inrush pulls 170…230 VA at 0.55 power factor on 60 Hz. That inrush spike matters for the control transformer sizing — a small transformer may drop voltage and fail to latch the contactor.
