Schneider Electric LA1-LB017 Contact Block

Schneider Electric LA1-LB017 is an auxiliary contact block designed to extend the signaling capability of LA1 TeSys contactors, allowing a compact, modular way to add a third contact bank to standard control circuits. It provides two normally open contacts and one normally closed contact, all wired through screw-clamp terminals rated for reliable field wiring in control panels, enabling flexible wiring topologies for status indication, interlocking, or sequencing in motor-control systems. The LA1-LB017 catalog number is documented by Schneider Electric as discontinued, with commercialization ending on November 30, 2022, while after-sales service and spare parts continue to be offered through the product's end of life to support existing installations.
