It's the coil that pulls in and holds the main contactor — no built-in suppressor module, so you'll need to handle flyback suppression externally if the circuit demands it. Opening time runs 100 to 130 ms; closing time is tighter at 70 to 80 ms. That's the mechanical travel time — the actual arc extinction depends on the contactor it's paired with. ## Sourcing reality — obsolete, but findable Schneider Electric lists this coil as obsolete. No official successor order code appears in the record. That means the normal new-channel supply is closed — your procurement path is surplus, broker, or a pull from decommissioned gear. The coil is rated for 150 V DC control voltage, with an operational range of 0.85 to 1.1 Uc at 55 °C, and dropout between 0.2 and 0.4 Uc. Ambient operating temperature is -5 to 55 °C. These specs matter for verifying fit against your existing contactor base — if your line runs at 125 V DC or 170 V DC nominal, this coil won't hold in. ## What to check before ordering No built-in suppressor means the coil's inductive kickback lands on whatever drives it. If your panel uses a PLC output or a solid-state relay to fire the contactor, you'll want a free-wheeling diode or a varistor across the coil terminals — standard practice for DC coils without internal suppression. The part is a single-unit package, device short name LX4FX. It's a service part, not a new-design component — expect to verify mechanical fit against your existing contactor frame before committing the BOM line.","metaTitle":"TeSys LX4FX150 Contactor Coil, 150 V DC, Obsolete","metaDescription":"TeSys LX4FX150 contactor coil, 150 V DC control voltage, 100-130 ms opening time.
