Schneider Electric LA1LB0311 Auxiliary Contact Block

The Telemecanique LA1LB0311 Auxiliary Contact Block adds one normally open and one normally closed auxiliary contact to contactors and combination motor starters, expanding control capability in industrial motor control systems. It mounts on the left side with screw clamp terminals and provides instantaneous auxiliary signaling for control circuit expansion. Rated for up to 690 VAC Ue, with a conventional free air thermal current (Ith) of 10 A and an insulation voltage (Ui) of 690 VAC (IEC) or 600 VAC (UL/CSA), this block is designed for Telemecanique integral self-protected controllers and compatible contactors. Common in motor control centers, conveyors, pumps, compressors, packaging machinery, and industrial control panels, it is a discontinued legacy model (LA1LB0311).
