The LX1LD127 is a replacement coil for the TeSys Integral series of motor starters and contactors from Schneider Electric. It is a 127 V AC 50 Hz control coil, meaning it is designed to be energized by a 127 V AC control circuit at 50 Hz to pull in the contactor's armature. The coil draws 350 to 400 VA inrush at 50 Hz with a power factor of 0.55 to pull in, then settles to 20 to 30 VA hold-in power at 50 Hz with a power factor of 0.28. The DC resistance measures 9.8 Ohm at 68 °F (20 °C), and the inductance of the closed circuit is 2.13 H. Operational voltage range is 0.85 to 1.1 times the rated control voltage (Uc) at up to 131 °F (55 °C); dropout occurs between 0.25 and 0.7 Uc. This means the coil will hold in reliably down to about 108 V AC and will drop out somewhere between 32 and 89 V AC, depending on temperature.

Frequently asked questions
What replaces the LX1LD127?
Schneider Electric does not list a direct official successor for this order code. For a replacement, you would need to identify the specific TeSys Integral contactor or starter it came from and select a current-production coil from the TeSys range with the same voltage and frequency rating. We can assist with that cross-reference on an RFQ.
What are the key electrical ratings of the LX1LD127?
It is a 127 V AC 50 Hz control coil with 9.8 Ohm DC resistance, 350-400 VA inrush, and 20-30 VA hold-in power. The operational voltage range is 0.85 to 1.1 Uc, and dropout is 0.25 to 0.7 Uc.
