Schneider Electric SE LA6DK3 Mechanical Latch

Description:

The Telemecanique LA6DK3 Mechanical Latch is used in industrial motor control systems to mechanically latch compatible TeSys D contactors in the energized position without continuous coil power. Commonly installed in motor control centers (MCCs), conveyor systems, pumps, compressors, and industrial control panels. Maintenance teams, OEMs, and system integrators use this mechanical latch for repair, replacement, retrofit, or industrial automation maintenance.

Applications:

The Telemecanique LA6DK3 Mechanical Latch is commonly used in industrial facilities to provide mechanical latching and remote unlatching of contactors in equipment such as conveyors, pumps, compressors, HVAC systems, material handling equipment, robotics, production lines, MCCs, and industrial control panels where dependable latching, reliable machine control, process monitoring, and electrical interlocking are essential.
