Rated at 20 V DC control voltage, this coil is specific to DC control schemes — it will not work on an AC control transformer without a rectifier. The hold-in power consumption is 22 W at 68 °F (20 °C), with an inrush of the same value, meaning no separate pick-up/hold-in curve to manage. The coil has no built-in suppressor module, so you need to add a free-wheeling diode or varistor across the coil if the driving circuit requires transient suppression. That is a fast cycling rate — suitable for applications like conveyor indexing or rapid valve actuation, but the thermal limit at elevated ambient temperature should be respected. The control circuit voltage limits are: dropout at 0.1 to 0.3 Uc (2 to 6 V DC) and operational at 0.85 to 1.1 Uc (17 to 22 V DC) at below 131 °F (55 °C). This means the coil will reliably pick up at around 17 V DC and will drop out below about 6 V DC, giving a wide hysteresis that prevents chatter on a noisy DC bus. ## Where this class of part is used Contactor coils like this one are the replaceable actuation element in TeSys Deca contactors. They are used in motor control centers, panel boards, and industrial machinery where the contactor itself is a fixed installation and the coil is a serviceable wear item. The 20 V DC rating places it in DC control systems, common in battery-backed or PLC-driven panels.","metaTitle":"Schneider Electric LX4D7ZD TeSys Contactor Coil, 20 V DC, Ob","metaDescription":"Obsolete Schneider Electric LX4D7ZD TeSys Deca contactor coil, 20 V DC standard, for 80 A contactor.
