The LX1FF032 is a replacement coil for the TeSys F contactor range, designed for 32 V AC 50 Hz control circuits. It is the component that pulls in and holds the contactor armature — without it, the main power poles don't close. Rated for 32 V AC at 50 Hz, this coil draws 550 VA inrush at 68 °F (20 °C) with a cos phi of 0.3, then settles to 45 VA holding power. The 12 to 16 W heat dissipation at 50 Hz means the panel designer needs to account for that thermal load inside the enclosure, especially if multiple contactors are ganged.
Key Specs for Fit Verification
Operating time is 23 to 35 ms closing and 5 to 15 ms opening. The coil has no built-in suppressor module, so if your application requires EMI suppression or flyback protection, you will need to add an external RC snubber or varistor across the coil terminals. The control circuit voltage limits are drop-out at 0.35 to 0.55 Uc and operational at 0.85 to 1.1 Uc at 50/60 Hz. Average coil resistance is 0.51 Ohm at 68 °F (20 °C), and the inductance of the closed circuit is 0.07 H. Ambient air temperature range for operation is 23 to 131 °F (-5 to 55 °C).
