The LX1D6SF5 is a contactor coil from the TeSys Deca series, designed to mount onto the corresponding contactor frame. It operates on a 500 V AC 50 Hz control circuit, drawing 200 VA inrush at 50 Hz cos phi 0.75 and 20 VA holding at 50 Hz cos phi 0.3, both measured at 68 °F (20 °C). The coil resistance sits at 668 Ohm at 20 °C, with an inductance of 38 H when the circuit is closed. It's built without a built-in suppressor module, so you'll need to add external suppression if the application demands it—common practice for inductive load switching in panel builds.
Voltage Tolerances and Thermal Behaviour
The coil's control circuit voltage limits are defined: drop-out occurs between 0.3 and 0.6 Uc at 50/60 Hz, and operational pick-up requires 0.8 to 1.1 Uc at 50 Hz (0.85 to 1.1 Uc at 60 Hz), all at temperatures below 131 °F (55 °C). This means at nominal 500 V AC, the coil drops out somewhere between 150 V and 300 V, and needs at least 400 V to pull in reliably at 50 Hz. Heat dissipation runs 6 to 10 W at 50/60 Hz—enough to warm the panel locally, so ensure ventilation around the contactor stack. Ambient temperature range for operation is 23 to 140 °F (-5 to 60 °C).
