The Schneider Electric TeSys LA1LC072B is an instantaneous undervoltage trip that drops out the contactor or motor starter when control voltage falls below a set threshold. It operates on 24 V AC 50/60 Hz control circuits, tripping when the voltage decays to between 0.35 and 0.7 Uc.
The coil draws 8 VA inrush and holds at 4 VA steady-state. Control circuit voltage limits are 0.8 to 1.1 Uc. Supplied as a set of 10 units.
TeSys is Schneider Electric's family of motor control and protection components — contactors, starters, overload relays, and auxiliary blocks like this undervoltage trip. The LA1LC072B belongs to the TeSys Integral sub-range.
