Schneider Electric LUA1C20 Auxiliary Contact Block

Schneider Electric LUA1C20 is an auxiliary signalling contact block designed for TeSys Ultra starter controllers. This two-contact accessory provides two normally open (NO) contacts for fault signaling and control-circuit feedback, wired through screw clamp terminals for reliable field connections. Rated for 690 VAC or DC, it integrates with TeSys U starters to deliver status signals without occupying main contact positions, enabling straightforward PLC or interlock wiring in motor-control applications. The LUA1C20 is intended to enhance monitoring and safety interlocks in industrial electrical installations by providing dedicated signaling contacts that mirror the state of the main starter.
