Can TeSys F range coil LX4FG090 be used for 110V DC.
The LX4FG090 is a DC coils marked as 90 VDC and it can be used as a "wide range" coil for 110 VDC.
Minimum voltage to close the contactor : 0.85 x 90 = 76.5 VDC.
This minimum operating voltage ( 0.7 x 110 VDC) makes it "wide range" when used at 110 VDC.
However, it is important to note the restriction of use at 110 VDC, as operating rate : 60 cycles per hour at 55°C max.
