The Schneider Electric LV839248 is an XF com communicating closing voltage release — a drawout-mounted closing coil for MasterPact MTZ air circuit breakers. It controls the breaker's close operation via a 48 V AC (50/60 Hz) or 48-60 V DC control circuit, with a threshold tripping voltage range of 0.85 to 1.1 Un. Its communicating control type means it integrates with the MTZ's digital ecosystem — the coil signals status (coil powered, error, electrical push-button activated, ready to close or open) back to the control system, not just a bare solenoid pull.
Schneider has marked the LV839248 as obsolete.
Integration notes for the drawout cradle
Drawout mounting means the coil installs into the MTZ's removable cradle, not the fixed housing — it travels with the breaker element when racked out. Holding power is 4.5 VA / 4.5 W, so the control transformer or DC supply needs to sustain that continuously while the breaker is closed.
