The LX1FG084 is a replacement contactor coil from the TeSys F range, designed for 84 V AC 50 Hz control circuits. It is the energizing component for a TeSys F contactor, drawing inrush power of 805 VA at 50 Hz and holding at 55 VA (cos φ 0.3, at 68 °F). The coil operates with a closing time of 20...35 ms and an opening time of 7...15 ms. Control circuit voltage limits are drop-out at 0.35...0.55 Uc and operational at 0.85...1.1 Uc at 131 °F (55 °C).
Key Ratings and Their Meaning for Fit
The coil dissipates 18...24 W at 50 Hz. For a panel-builder or MRO planner: this heat load must be accounted for in the enclosure thermal budget, especially if the contactor cycles near its maximum operating rate of 2400 cycles per hour at 131 °F (55 °C). The mechanical durability of 10 Mcycles means the coil itself is not the life-limiting component in most cyclic applications. The coil has no built-in suppressor module. For a controls integrator: this means an external RC snubber or varistor must be added across the coil terminals if the control circuit includes a PLC output or solid-state relay, per standard wiring practice for inductive loads. The average resistance is 2.22 Ω at 68 °F (20 °C), and the inductance of the closed circuit is 0.37 H.
