What this coil does and where it lands
The LX1D25240 is a coil for contactor — the electromagnetic actuator that pulls the contactor's main poles closed when energised. It's the replaceable part on the front of a TeSys contactor; when the coil burns or the line voltage changes, you swap this, not the whole contactor.
Sourcing and fit check
Sourced to order against the BOM through independent distribution. The coil is a field-replaceable unit; confirm the contactor frame and coil voltage before committing the order.
