Schneider Electric LADN22 Auxiliary Contact Block

Description:

The Telemecanique LADN22 Auxiliary Contact Block is used in industrial motor control systems to provide two normally open and two normally closed auxiliary contacts for control, signaling, and electrical interlocking of compatible TeSys IEC contactors and control relays. Commonly installed in motor control centers (MCCs), conveyor systems, pumps, compressors, and industrial control panels. Maintenance teams, OEMs, and system integrators use this auxiliary contact block for repair, replacement, retrofit, or industrial automation maintenance.

Applications:

The Telemecanique LADN22 Auxiliary Contact Block is commonly used in industrial facilities to expand the control capabilities of contactors in equipment such as conveyors, pumps, compressors, packaging machines, HVAC systems, material handling equipment, robotics, production lines, MCCs, and industrial control panels where dependable machine control, reliable status indication, process monitoring, and electrical interlocking are essential.
