That voltage is the coil's nominal pick-up rating — it pulls the contactor in reliably at that level, and the hold-in power stays within the coil's thermal budget. The 51.9 Ohm average resistance at 68 °F (20 °C) and 4.18 H closed-circuit inductance tell you the steady-state current draw: about 3.3 A inrush dropping to under 0.5 A sealed. That matters for your DC supply sizing and for any suppression you add externally, because this coil ships without a built-in suppressor module. ## Duty cycle and environment Rated for 10 Mcycles mechanical — that's a long service life in a machine that cycles a few times a minute, but the maximum operating rate of 3600 cycles per hour at 140 °F (60 °C) sets the real limit: one cycle per second sustained, and you're at the thermal ceiling. No IP rating on a coil — it's inside the contactor envelope, so the contactor's own enclosure protects it.","metaTitle":"TeSys LX4D6QD Contactor Coil, 174 V DC","metaDescription":"TeSys LX4D6QD contactor coil, 174 V DC control voltage, 51.9 Ohm resistance, 10 Mcycles mechanical durability, active lifecycle.
