The LA1LC071U is a TeSys Integral shunt trip from Schneider Electric's TeSys range — an instantaneous voltage release that trips the parent contactor or circuit breaker when its control voltage is applied or drops below the dropout threshold. Rated for a 240 V AC 50 Hz control circuit, it draws 8 VA inrush and 4 VA hold-in power. The threshold tripping voltage is 0.35 to 0.7 Uc, meaning the release will unlatch the mechanism when the control voltage falls to roughly 84 to 168 V AC. The operating time is 10 ms or more — instantaneous, no intentional delay. The control circuit voltage limits are 0.7 to 1.1 Uc (168 to 264 V AC), so the shunt trip must see at least 168 V to stay latched during normal operation.
