Schneider Electric LC1D12BD DC Coil Contactor

Description:

The Telemecanique LC1D12BD Contactor with LADN22 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, packaging machinery, and automated production lines. Maintenance teams, OEMs, and system integrators use this assembly for repair, replacement, retrofit, or industrial automation maintenance.

Applications:

The Telemecanique LC1D12BD Contactor with LADN22 Auxiliary Contact Block is commonly used to control three-phase motors and industrial electrical loads in conveyors, pumps, compressors, fans, mixers, machine tools, packaging equipment, and material handling systems. The 24 VDC control coil provides reliable operation in PLC-based control panels, while the LADN22 auxiliary contact block expands the contactor with 2 NO and 2 NC auxiliary contacts for interlocking, signaling, and control logic functions.
