The maximum operating rate is 2400 cycles per hour at 131 °F (55 °C), which covers high-speed pick-and-place or conveyor indexing applications. ## Coil electrical characteristics Inrush power hits 1000 W at 68 °F (20 °C), then drops to 6 W holding. That inrush spike is short — the coil's average resistance shifts from 236 Ω inrush to 33750 Ω holding — so the control transformer or DC supply needs to handle the initial surge without drooping below the 0.85 Uc operational limit. The coil has no built-in suppressor module. If your control circuit drives inductive loads, you'll want an external flyback diode or RC snubber across the coil terminals to protect the DC output card from voltage spikes during de-energization. Drop-out voltage is 0.2 to 0.35 Uc at 131 °F (55 °C). It belongs to the TeSys F range, a modular contactor platform. If you're replacing a failed coil on an existing TeSys F contactor, the LX4FJ375 is the direct service-part match for the 375 V DC variant. No adapter or wiring modification needed.","metaTitle":"TeSys LX4FJ375 Contactor Coil, 375 V DC","metaDescription":"TeSys F contactor coil LX4FJ375, 375 V DC control circuit, 45-60 ms opening time, 10 Mcycles mechanical durability.
