It is a bare coil without a built-in suppressor module, so any RC snubber or varistor must be added externally across the coil terminals if the application requires EMI suppression or inductive-load protection for the driving PLC output. Rated for 100-110 V AC at 50/60 Hz, it draws 300 VA inrush at 50 Hz (cos φ 0.8) and settles to 22 VA hold-in power (cos φ 0.3). That 13:1 ratio between pick-up and sealed power means the control transformer must be sized for the inrush peak, not the hold-in steady state — a 100 VA transformer will drop its output voltage momentarily if the coil shares a circuit with other loads. ## Lifecycle reality and sourcing posture If you are validating a new design or a replacement for an existing panel, the coil's mechanical durability of 8 Mcycles and maximum operating rate of 2400 cycles/hour at 60 °C give a solid baseline for expected service life, but the obsolete status means you should evaluate a form-fit-function equivalent from the current TeSys range before committing to a long-term spares plan. ## Electrical characteristics that govern fit The coil's average resistance is 1.24 Ω at 20 °C, and its closed-circuit inductance is 0.09 H. These values matter for sizing the control transformer and for calculating the back-EMV if you add an external suppressor — a standard RC snubber across the coil will see that inductance as the load. Drop-out voltage is 0.3 to 0.6 Uc at 50 Hz; operational range is 0.85 to 1.1 Uc at 50 Hz below 55 °C. In practice, if your control supply sags below about 85 V AC, the coil may not pick up reliably, and it will drop out below about 55 V AC. Heat dissipation runs 3 to 8 W at 50 Hz depending on the coil state. In a densely packed panel with multiple contactors running continuously, that heat adds up — allow adequate ventilation or derating if ambient inside the enclosure approaches 60 °C.","metaTitle":"Schneider LX1D8K7 TeSys Contactor Coil, 100-110 VAC","metaDescription":"Obsolete TeSys Deca contactor coil LX1D8K7, 100-110 VAC 50/60 Hz. 300 VA inrush, 22 VA hold.
