The Schneider LA1LC071E is a shunt trip from the TeSys range, designed to remotely trip a contactor or circuit breaker by applying a control voltage. The control circuit voltage limits are 0.7 to 1.1 times Uc (the rated control voltage), and the threshold tripping voltage is 0.35 to 0.7 Uc, meaning it will reliably trip even if the control supply drops to about 17 V AC. Inrush power is 8 VA AC, holding at 4 VA AC once energised.
If you need a shunt trip for a TeSys contactor at 48 V AC, a cross-reference to a current TeSys or TeSys Deca part number will need to be validated against the specific contactor frame and mounting. The LA1LC071E uses screw terminals and is a set of 10 units per package.
This shunt trip mounts onto the contactor or breaker in the TeSys range — typically the Integral or TeSys D / F / K frames — using the dedicated accessory slot. The screw terminals accept standard control wiring; no special tooling needed. Because it is a control accessory, it sits inside the panel, not in the main power path.
