The LV839251 is a communicating closing voltage release — an XF com coil — for MasterPact MTZ drawout circuit breakers. It operates on a 277 V AC 50/60 Hz control circuit and draws 4.5 W / 4.5 VA holding power. The response time varies by frame: 55 ms ±10% for MTZ1, 70 ms ±10% for MTZ2, and 80 ms ±10% for MTZ3. This is a drawout-mounted part, meaning it plugs into the breaker cradle rather than being hardwired into the panel — a clean swap when the breaker is racked out.
