The TeSys LX4FL340 is a contactor coil — the replaceable solenoid that pulls in the main contacts of a TeSys contactor. It's a DC low-consumption coil rated for 340 V DC control voltage, with an opening time of 40 to 50 ms and a closing time of 60 to 70 ms. The coil has no built-in suppressor module, so you'll need to add external flyback diode or RC snubber across the coil terminals to protect the control circuit from inductive kickback when de-energizing. Control voltage limits: dropout occurs at 0.2 to 0.35 Uc (68 to 119 V DC) at 131 °F (55 °C); operational range is 0.85 to 1.1 Uc (289 to 374 V DC) at the same temperature. Ambient operating temperature is -5 to 55 °C (23 to 131 °F).
Because this is a service part (category 18401-WORLD SERVICE PARTS(CTR ACCESS)), it was originally intended for aftermarket replacement in existing TeSys contactors. If you're kitting a repair for a line that already uses this coil, the obsolete status means you should verify availability before committing the BOM line.
One unit per package — just the coil itself, no mounting bracket, no suppressor module, no accessory pack. The kit is complete for what it is: a bare replacement coil. No holes in the box, but you supply the external suppression.
