It operates on a 34-37 V DC control circuit, drawing 48 W hold-in power at 68 °F (20 °C) with an inrush of 733 W at the same temperature. The coil is a low-consumption type, compatible with both AC (40-400 Hz) and DC control circuits, though this variant is specifically wound for 34-37 V DC. It has no built-in suppressor module, so you will need to add external flyback suppression — a standard diode or RC snubber across the coil terminals — to protect the control circuit from the inductive kick when the contactor drops out. Operating time is 60 ms opening and 20 ms closing, which is typical for a contactor of this frame size. The coil dissipates 22.8-27.8 W of heat, so ensure adequate ventilation in the enclosure — especially if multiple contactors are ganged together. The control circuit voltage is 34-37 V DC, with operational limits of 0.85-1.1 Uc at 131 °F (55 °C) — meaning the coil will pick up reliably between about 29 V and 41 V DC at that temperature. Drop-out occurs at 0.3-0.5 Uc (roughly 10-18.5 V DC), so the contactor will drop out cleanly on a sagging supply. This is important if your DC bus is shared with other loads that may cause voltage dips. That is about one operation every two seconds — fine for most motor starting and switching duty, but if you are cycling faster than that (e.g., in a rapid-reversing application), you will exceed the rated rate and risk premature coil failure. The ambient temperature range for operation is 23 to 131 °F (-5 to 55 °C). This is a standard industrial range — the coil will work in an unheated panel in most climates, but if your enclosure sits in direct sun or near a furnace, you need to check the internal temperature stays below 55 °C.","metaTitle":"TeSys LX9FL915 Specific Contactor Coil, 34-37 V DC, Obsolete","metaDescription":"TeSys LX9FL915 specific contactor coil for TeSys F contactors. 34-37 V DC low consumption coil.

The TeSys F range is still active, and a standard-voltage coil (with built-in suppression) may fit the same contactor frame, but you must verify the mechanical fit and electrical ratings against your specific contactor model. The LX9FL915 is a low-consumption 34-37 V DC coil without suppression — a standard coil will differ in voltage, power draw, and suppression circuitry."},{"question":"What is the control circuit voltage for the LX9FL915?","answer":"The control circuit voltage is 34-37 V DC.
