It monitors the control voltage at 240 V AC 50 Hz and trips the starter if the voltage drops below 0.35 to 0.7 times the rated control voltage (Uc), with a deliberate 0.2 s time delay to ride through brief sags without nuisance tripping. The 0.2 s delay is the key spec for a sourcing buyer: it prevents the starter from dropping out on a momentary dip (like a large motor starting elsewhere on the same line), but still clears on a sustained undervoltage that could cause contactor chatter or single-phasing damage. It ships as a set of 10 units, which is the standard packaging quantity for these service-part undervoltage trips — order one line item and you get ten pieces on the shelf. ## Control circuit fit and limits The control circuit voltage limits are 0.7 to 1.1 times Uc (240 V AC), so the trip coil holds in reliably between 168 V and 264 V AC — a standard tolerance band for industrial control transformers. Inrush power draw is 8 VA AC; hold-in power is 4 VA AC — low enough that a typical 100 VA control transformer can power several of these trips plus contactor coils without oversizing.","metaTitle":"Schneider TeSys LA1LC070U Undervoltage Trip, 240 V AC, 0.2 s","metaDescription":"Schneider TeSys LA1LC070U undervoltage trip for Integral motor starters. 240 V AC 50 Hz control, 0.2 s delay, active production.
