Schneider Electric LC1D2510 Three Phase Contactor

Description:

The Telemecanique LC1D2510 Contactor with LA1DN20 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 LC1D2510 Contactor is commonly used to control three-phase motors and industrial electrical loads in conveyors, pumps, compressors, industrial fans, mixers, packaging equipment, machine tools, and material handling systems. The addition of the LA1DN20 top-mounted auxiliary contact block provides two normally open auxiliary contacts for interlocking, sequencing, status indication, and PLC interface functions, making the assembly well suited for industrial control panels and OEM automation equipment.
