The LX1D84LSE is the control coil module for a TeSys Deca Advanced 4-pole contactor — specifically the LC1DT200A frame. It's the replaceable coil assembly, not the full contactor, so you're swapping only the electromagnet section while keeping the power poles and arc chambers in place. Rated for 200...500 V AC/DC control circuits, which covers most 230/400/480 V control transformers without needing a separate coil tap. Coil type is wide-range AC/DC — meaning it accepts both supply types across the full 200-500 V band without a rectifier module or voltage selector. Control voltage limits are 0.8 Uc min to 1.1 Uc max at ambient below 60 °C, so at 400 V nominal the dropout threshold sits around 320 V and pickup around 440 V.
Power draw and thermal budget
Inrush hits 120 W / 170 VA at 20 °C, then settles to a hold-in of 5.1 W / 16.5 VA. That 3 W continuous heat dissipation matters when you're stacking multiple contactors in a sealed panel — it's low enough for most enclosures without forced ventilation, but worth checking against your thermal rise calc if you're running 20+ units in a single cabinet. Mechanical durability is rated at 8 million cycles — that's the contactor frame's mechanical life, not the electrical switching life under load. For reference, a PLC cycling a conveyor once every 10 seconds would hit 8 Mcycles in about 2.5 years of continuous operation.
Mounts onto the LC1DT200A contactor base via the standard TeSys Deca clip system — no tools needed for the coil swap, but you'll want the contactor de-energized and the auxiliary contacts disconnected before prying the module off. The 4-pole configuration means the coil module spans the full width of the contactor; verify mechanical interlock clearance if you're pairing two units for reversing duty.
