The LA1LC030 is a TeSys-series auxiliary contact block from Schneider Electric, providing one normally-open instantaneous contact for use with TeSys contactors and starters. It mounts on the left side of the contactor, adding a single NO auxiliary circuit without increasing the panel depth — critical for tight DIN-rail layouts where every millimeter counts.
AC-15 rated operational power ranges from 160 VA at 48 V up to 600 VA at 220–240 V, covering pilot-duty loads like contactor coils and solenoid valves; DC-13 ratings span 28 W at 440 V to 150 W at 48 V, suitable for DC control circuits in older panel designs. Terminals accept 1.5 mm² and 2.5 mm² conductors via screw clamp — standard for control wiring in IEC panels, but the smaller terminal limits the wire size for the common loop return.
Obsolete — sourcing reality for a critical spare
Schneider has marked the LA1LC030 as obsolete. For installed TeSys contactors still in service, this auxiliary block is the exact spare to keep one in the cabinet before it fails — the NO contact is the most common failure point in a control loop, and a missing spare means downtime while sourcing through surplus channels.
