It's a low-consumption coil without a built-in suppressor module, so you'll need to add a free-wheeling diode or RC snubber externally if the circuit requires it. The coil pulls 733 W inrush at 20 °C and holds at 48 W — the inrush is a brief spike, but your DC supply needs to handle that surge without dropping below the 85% operational limit. The control voltage limits are tight: operational from 0.85 to 1.1 Uc (255 to 367 V DC at 55 °C), drop-out between 0.3 and 0.5 Uc (90 to 167 V DC). If your DC bus sags below 255 V during a brownout, the contactor drops — plan your control transformer or UPS accordingly. Opening time is 60 ms, closing 20 ms — fast enough for most motor and resistive load switching, but if you need arc-sync or zero-cross switching, this coil's mechanical speed is the limiting factor, not the electronics. Rated for 5 million mechanical cycles at a maximum operating rate of 1800 cycles per hour at 70 °C. That's about one operation every two seconds — fine for conveyor cycling or pump start/stop, but not for high-speed pick-and-place or welding gun duty. Heat dissipation runs 22.8 to 27.8 W at full hold — that's non-trivial in a sealed panel. If you're grouping multiple TeSys F contactors, account for this in your thermal budget to avoid derating the coil's ambient temperature range of -5 to 55 °C.","metaTitle":"Schneider Electric LX9FL934 TeSys F contactor coil, 300-334","metaDescription":"LX9FL934 is a specific contactor coil for TeSys F contactors.
