It monitors a 415-440 V AC control circuit (50/60 Hz) and trips after a 0.2 s time delay, preventing nuisance dropouts on brief sags while protecting against sustained undervoltage. The trip threshold is adjustable between 0.35 and 0.7 times the control voltage Uc, so on a 440 V line it would trigger between roughly 154 V and 308 V. The coil draws 8 VA inrush and 4 VA holding, and the control voltage must stay within 0.8 to 1.1 Uc for normal operation. The TeSys Integral range includes several undervoltage trip variants at different voltage ratings; the LA1LC070N is the 415-440 V AC version. The 0.2 s time delay is the key fit parameter — it distinguishes this undervoltage trip from instantaneous versions. On a line with motor starters that must ride through brief voltage dips (e.g., during a large motor start elsewhere in the plant), the delay prevents unnecessary dropouts. If your existing starter uses an instantaneous UVR, swapping to this delayed type changes the protection coordination. The 415-440 V AC control voltage range is specific to 400 V class systems where the control transformer taps at 415 V or 440 V. It will not work on 230 V or 480 V control circuits without a transformer change. The 50/60 Hz dual rating covers both mains frequencies without derating. Sold as a set of 10, which is the standard packaging for these trip accessories — not a single unit. Factor that into your order quantity.","metaTitle":"Schneider LA1LC070N TeSys Undervoltage Trip, 415-440 V AC, O","metaDescription":"Schneider LA1LC070N TeSys undervoltage trip, 415-440 V AC 50/60 Hz, 0.2 s delay.
