The Schneider LA1LC070M is an undervoltage trip accessory for the TeSys Integral starter range. It monitors the control circuit voltage and trips the starter when voltage drops to 0.35...0.7 Uc, with a built-in 0.2 s time delay to ride through brief sags. Control circuit voltage is 220...230 V AC at 50 Hz or 220...240 V AC at 60 Hz.
The undervoltage release trips between 0.35 and 0.7 Uc. Hold-in power consumption is 4 VA AC; inrush is 8 VA AC.
Deployment context
This accessory mounts directly onto a TeSys Integral starter base, typically inside a motor control center or panel enclosure. It is sold as a set of 10, which suits panel builders or MRO planners stocking spares for a bank of starters.
