The LX9FL926 is a specific contactor coil from the TeSys F range, designed as a replacement coil for TeSys F contactors. It operates on a 127 V DC control circuit, with low-consumption AC 40...400 Hz and DC control circuit types. This coil has an opening time of 60 ms and a closing time of 20 ms, with a maximum operating rate of 1800 cycles per hour at 158 °F (70 °C). Mechanical durability is rated at 5 Mcycles.
Electrical characteristics and thermal management
The coil draws an inrush power of 733 W at 68 °F (20 °C), with an inrush resistance of 20.8 Ohm. Holding power at 68 °F (20 °C) is 48 W, with a holding resistance of 167 Ohm. Heat dissipation ranges from 22.8 to 27.8 W. Control circuit voltage limits are 0.85...1.1 Uc for operation and 0.3...0.5 Uc for drop-out at 131 °F (55 °C). The coil does not include a built-in suppressor module, so external suppression is needed for inductive load switching. Inductance of the closed circuit is 1.2 H. Ambient air temperature for operation is 23...131 °F (-5...55 °C). The coil technology is without built-in suppressor module.
