It's the part that keeps a motor from re-accelerating after a brownout without a deliberate reset. The trip threshold is 0.35 to 0.7 Uc, meaning it releases when the control voltage drops to between 35% and 70% of its rated coil voltage. The coil holds in from 0.8 to 1.1 Uc, so it won't drop out on a minor dip — only on a genuine undervoltage event. Inrush power draw is 8 VA AC; once sealed, hold-in drops to 4 VA AC. That's light on the control transformer — a detail worth checking if you're retrofitting into a crowded panel with a shared 50 VA supply. If you need a drop-in replacement, the closest functional match would be another TeSys undervoltage trip with the same voltage range and instantaneous release — but pinout and mounting footprint must be verified against your existing starter or contactor. The part ships as a set of 10, so one order code covers a full kit of undervoltage trips — no holes in the box for a multi-starter line. One unit per package, set of 10 per order code. No time delay module — it's the instantaneous variant. The device short name is LA1LC.","metaTitle":"Schneider TeSys LA1LC072EJ Undervoltage Trip, Obsolete","metaDescription":"Schneider TeSys LA1LC072EJ undervoltage trip, instantaneous, without time delay.
