Product details

The Schneider Electric LA1LC071Q is a shunt trip from the TeSys range, designed as a control accessory for remote tripping of circuit breakers or contactors. It operates as an instantaneous voltage release — apply the control voltage and it trips the parent device without any intentional time delay. Rated for a control circuit voltage of 380...400 V AC at 50/60 Hz, it draws 8 VA inrush and 4 VA hold-in power. The trip threshold sits at 0.35...0.7 Uc, meaning it will release the mechanism when the control voltage drops to roughly 133-280 V on a 380 V nominal supply. Operating time is >= 10 ms.

Supplied as a set of 10 units, with screw terminal connections for panel wiring.

Deployment context

The screw terminals accept standard panel wiring; no special tooling needed. The instantaneous trip characteristic suits applications where a fault or emergency-stop signal must clear the main contacts without delay.

Frequently asked questions

What is the control voltage rating for this shunt trip?

The control circuit voltage is 380...400 V AC at 50/60 Hz. The operating voltage range is 0.7...1.1 Uc, so it will function between approximately 266 V and 440 V AC. The trip threshold is 0.35...0.7 Uc.

Does this shunt trip have a time delay?

No, it is an instantaneous shunt trip without time delay. Operating time is >= 10 ms from application of the control voltage.

What is the power consumption of the LA1LC071Q?

Inrush power is 8 VA AC; hold-in power consumption is 4 VA AC.

How is the LA1LC071Q packaged and terminated?

Supplied as a set of 10 units. Connections are via screw terminals.
