Schneider Electric Telemecanique LC1D2501 Contactor

Description:

The Telemecanique LC1D2501 Contactor with LA1DN11 Auxiliary Contact Block is used in industrial motor control and power switching systems. Commonly installed in motor control centers (MCCs), conveyor systems, pumps, compressors, HVAC equipment, and automated production lines. Maintenance teams, OEMs, and system integrators use this assembly for repair, replacement, retrofit, or industrial automation maintenance.

Applications:

The Telemecanique LC1D2501 Contactor is commonly used to control three-phase motors and industrial electrical loads in conveyors, pumps, compressors, industrial fans, mixers, machine tools, packaging equipment, and material handling systems. Equipped with a 110/120 VAC control coil and a front-mounted LA1DN11 auxiliary contact block, it provides additional control contacts for interlocking, status indication, alarm circuits, and PLC interface functions in industrial control panels and OEM machinery.
