It is a control circuit coil rated for 84 V AC at 50 Hz and 100 V AC at 60 Hz, with a 50/60 Hz control circuit type. The coil is rated for 84 V AC 50 Hz / 100 V AC 60 Hz, meaning it is designed for a control supply that delivers approximately 84 V at 50 Hz line frequency or 100 V at 60 Hz. The control voltage limits are specified as drop-out at 0.35...0.55 Uc and operational at 0.85...1.1 Uc at 55 °C, so the coil will reliably pick up at 71.4 V (50 Hz) and drop out between 29.4 V and 46.2 V. This is critical for ensuring the contactor does not chatter or fail to close on a marginal supply. Inrush power draw is 550 VA at 50 Hz (cos φ 0.3) and 650 VA at 60 Hz; hold-in power is 45 VA at 50 Hz and 55 VA at 60 Hz. The inrush figure governs the sizing of the control transformer and any series protection — a transformer rated for the hold-in VA alone will saturate on the inrush peak. Heat dissipation is 12...16 W at 50 Hz, which must be considered in enclosed panel thermal calculations. Operating time is 23...35 ms closing and 5...15 ms opening, with a maximum operating rate of 2400 cycles per hour at 55 °C. ## Coil technology and integration notes The coil is supplied without a built-in suppressor module. For applications with inductive load switching or where the coil is driven by a PLC output or solid-state relay, an external RC snubber or varistor across the coil terminals is recommended to limit voltage transients and extend the life of the driving device. The average resistance is 3.73 Ω at 20 °C, and the inductance of the closed circuit is 0.49 H. ## Environmental and packaging The part is packaged as a single unit.","metaTitle":"TeSys LX1FF084 Contactor Coil, 84..100 V AC, Obsolete","metaDescription":"Obsolete TeSys F contactor coil LX1FF084, 84 V AC 50 Hz / 100 V AC 60 Hz, 50/60 Hz control circuit.

For a direct replacement, a cross-reference against the TeSys F contactor frame size and the required control voltage (84 V AC 50 Hz / 100 V AC 60 Hz) would be needed. The LX1FF084 is a specific coil variant; a parametric search for a TeSys F coil with matching voltage and frequency ratings is the recommended approach."},{"question":"What is the control voltage rating of the LX1FF084?","answer":"The coil is rated for 84 V AC at 50 Hz and 100 V AC at 60 Hz, with a control circuit type of AC 50/60 Hz."},{"question":"Does the LX1FF084 include a built-in coil suppression module?","answer":"No, the coil technology is specified as 'Without built-in suppressor module'.
