It operates on an 80...88 V DC control circuit and is classified as low consumption. This coil draws 550 VA inrush at 20 °C and holds at 31 VA, with heat dissipation between 15 and 18.3 W during continuous operation. The opening time is 60 ms and closing time is 50 ms, which matters when coordinating contactor timing in a motor starter or reversing circuit. ## Coil voltage and control circuit Rated for 80...88 V DC, the coil holds in from 0.85 to 1.1 Uc at 55 °C and drops out between 0.3 and 0.5 Uc. That dropout threshold is low — about 24 to 40 V — so the contactor stays pulled in during a sag, but will drop cleanly on a loss of control voltage. There is no built-in suppressor module, so you need to add an external flyback diode or RC snubber across the coil if the control circuit drives inductive loads like a PLC output or relay. Without it, the back-EMF from the coil can damage solid-state outputs. ## Integration notes Maximum operating rate is 3600 cycles per hour at 70 °C. The coil is AC and low-consumption DC compatible across 40 to 400 Hz — but note the DC voltage range is tight at 80...88 V. Verify your control transformer or DC supply stays within that band, especially under load.","metaTitle":"TeSys LX9FK923 Specific Contactor Coil, 80..88 V DC, Low Con","metaDescription":"Active TeSys F specific contactor coil. 80..88 V DC, low consumption. 60 ms opening, 50 ms closing.
