Coil for TeSys contactor service — 570 V AC 50 Hz
The LX1LB570 is a replacement coil from the Schneider TeSys range, designed for contactors requiring a 570 V AC 50 Hz control circuit. It is the LX1 form-factor coil, a standard service part for maintaining TeSys contactor assemblies in the field. Rated for 570 V AC at 50 Hz, this coil pulls 75 VA inrush and drops to 8 VA sealed — the inrush figure is what the contactor's control transformer and wiring must handle at pick-up, while the sealed VA determines continuous heat dissipation in the panel. With an average resistance of 2728.08 Ω at 20 °C and an inductance of 6.6 H, the coil's DC resistance and inductive time constant are defined — useful for verifying coil integrity with an ohmmeter during commissioning or troubleshooting a line-down contactor.
