It operates on a 100-130 V AC/DC control circuit and signals coil powered, electrical push-button activated, error, ready to close, or open states. Mounting is drawout, meaning it plugs into the breaker cradle without hardwiring the release itself. Schneider Electric lists the LV839249 as obsolete. Holding power is 4.5 W. Threshold tripping voltage is 0.85 to 1.1 Un. ## Integration note Response time varies by frame: 55 ms ±10% on MasterPact MTZ1, 70 ms ±10% on MTZ2, 80 ms ±10% on MTZ3. That spread matters if you are coordinating closing sequences across multiple breakers — the MTZ3 takes nearly 50% longer to close than the MTZ1. The drawout form factor means the release stays with the cradle, not the breaker; swapping a breaker does not disturb the control wiring.","metaTitle":"LV839249 XF com communicating closing voltage release, 100-1","metaDescription":"LV839249 is an obsolete XF com communicating closing voltage release for MasterPact MTZ drawout breakers.
