Schneider Electric LA1LC0129 Contact Block

Schneider Electric LA1LC0129 Contact Block is an instantaneous auxiliary contact block in the LA1 family, designed to mount with Schneider Electric Integral/TeSys contactors to provide additional signaling contacts. The LA1LC0129 configuration comprises four normally closed (NC) contacts and one normally open (NO) contact, enabling monitoring and interlocking in control circuits without interrupting the main power path. As an add-on block for compatible contactors, it adds a compact set of auxiliary contacts for status indication, interlock logic, or fault signaling, helping automation systems track the energization state of the associated device. The product is described in Schneider Electric resources as an instantaneous auxiliary contact block for Integral assemblies, and is associated with the LA1LC series of auxiliary contact blocks.
