It's the service part you pull when the original coil on an FK-series contactor fails or you're building a spare kit for a panel that runs on a 150 V DC control bus. Opening time is 40 to 50 ms, closing time 60 to 70 ms — that's the mechanical stroke, not the arc extinction. If your application needs faster break than 50 ms, this coil won't get you there; you'd need a different contactor family with a faster armature. ## Control voltage limits — the real fit check The coil is rated for 150 V DC nominal, but the real operating window is 0.85 to 1.1 Uc at 131 °F (55 °C) — that's 127.5 to 165 V DC. Drop-out happens between 0.2 and 0.35 Uc, so 30 to 52.5 V DC. If your control supply sags below 127 V under load, the coil may drop out unexpectedly. No built-in suppressor module, so you'll need an external flyback diode or RC snubber across the coil to protect the PLC output or relay driving it.","metaTitle":"TeSys LX4FL150 Contactor Coil, 150 V DC, Active","metaDescription":"TeSys LX4FL150 contactor coil, 150 V DC control voltage, 40-50 ms opening time.
