It pulls in with a 0.989 Ω inrush resistance and holds at 222.5 Ω (both at 20 °C), with an operating time of 30-40 ms closing and 30-50 ms opening. The coil has no built-in suppressor module, so you'll need to add external flyback suppression — a freewheeling diode or RC snubber across the coil terminals — to protect the DC control circuit from the inductive kick when it drops out. The 27 V DC control voltage is the nominal coil rating, but the real operating window is wider: it picks up reliably between 0.85 and 1.1 times Uc (about 23-30 V DC at 55 °C), and drops out between 0.15 and 0.2 times Uc (about 4-5.4 V DC). That wide dropout margin means the contactor will release cleanly even with a sagging control supply — useful in battery-backed or lightly loaded DC buses.","metaTitle":"LX4FG027 TeSys contactor coil, 27 V DC, obsolete","metaDescription":"Obsolete TeSys LX4FG027 contactor coil, 27 V DC, 30-40 ms closing.
