It triggers at 0.35 to 0.7 times the rated control voltage (Uc), which for this variant is 380/400 V AC at 50/60 Hz. The built-in 0.2 s time delay prevents nuisance tripping during brief sags or switching transients. The 380/400 V AC control voltage is the nominal coil rating — the part operates reliably between 0.8 and 1.1 times Uc (304 to 440 V AC). The undervoltage threshold of 0.35 to 0.7 Uc means the trip activates when the line drops to roughly 133 to 280 V AC, depending on the adjustment setting. That 0.2 s delay is enough to ride through a momentary dip from a large motor start but short enough to drop the load before a prolonged brownout damages the contactor's coil. Inrush power is 8 VA AC; holding power drops to 4 VA AC once the armature seals, so the control transformer only needs to handle the inrush transient, not a continuous high draw. ## Deployment context This undervoltage release clips onto the front of a TeSys D or F contactor, occupying the same slot as a standard coil or auxiliary contact block. It does not add depth beyond the contactor's own envelope, so it fits existing panel layouts without re-spacing the DIN rail. The 0.2 s delay is factory-set and not field-adjustable — if the application needs a longer ride-through, a separate time-delay relay upstream is the usual workaround.","metaTitle":"Schneider LA1LC070Q TeSys Undervoltage Trip, 380/400 V AC, 0","metaDescription":"Active-production TeSys undervoltage release for 380/400 V AC 50/60 Hz circuits. 0.2 s time delay, set of 10.

The same physical part with a different coil voltage (e.g., 220/240 V AC or 24 V DC) would be a different order code; there is no pin-compatible substitute that changes only the delay. For a different time delay, you would need a separate timer module wired in series with a standard undervoltage release."},{"question":"What is the TeSys range for this part?","answer":"The LA1LC070Q belongs to the Schneider TeSys range, specifically the TeSys Integral series of control accessories for contactors and starters."},{"question":"What is the category code for the LA1LC070Q?","answer":"The category is 18402-WORLD SERVICE PARTS(CONTROL ACCESS), which covers service and replacement parts for control circuits."},{"question":"What compliance documentation is available for the LA1LC070Q?","answer":"As a Schneider TeSys component, the LA1LC070Q is covered by the standard RoHS and REACH declarations for the TeSys range.
