It operates on a 30 V DC control circuit with a DC low consumption design, drawing 0.81 Ohm inrush resistance and 206.3 Ohm holding resistance at 20 °C. The coil has an opening time of 45...60 ms and a closing time of 50...60 ms, with a control voltage drop-out range of 0.2...0.35 Uc and operational range of 0.85...1.1 Uc at 55 °C. It comes without a built-in suppressor module, so you'll need to add external suppression if your circuit requires it. The 30 V DC control voltage is the coil's nominal operating voltage — the circuit supplying it must stay within the 0.85...1.1 Uc operational limits at 55 °C to guarantee pickup. The drop-out threshold of 0.2...0.35 Uc means the contactor will release when the control voltage falls below roughly 6 to 10.5 V DC, which is a standard margin for DC coils. The operating time of 45...60 ms opening and 50...60 ms closing is typical for a DC contactor coil of this size. If your application needs faster switching, this coil won't deliver it — plan for the full window in your timing budget. The coil is rated for ambient air temperatures from 23...131 °F (-5...55 °C). If your panel runs hotter than 55 °C, you'll need to derate or relocate the coil.","metaTitle":"TeSys LX4FK030 Contactor Coil, 30 V DC, Obsolete","metaDescription":"TeSys LX4FK030 contactor coil, 30 V DC control voltage, DC low consumption design.
