Closing coil for MasterPact MTZ drawout
The Schneider Electric LV839254 is an XF closing voltage release designed for MasterPact MTZ drawout circuit breakers. It accepts a control voltage of 24 V AC at 50/60 Hz or 24–30 V DC, with a threshold tripping voltage of 0.85 to 1.1 Un, so it reliably closes the breaker within the standard control-power tolerance band.
Mounting mode is drawout, meaning the coil plugs into the MasterPact MTZ cradle without hardwiring. Holding power is 4.5 W / 4.5 VA.
Response timing across frame sizes
Response time varies by frame: 55 ms ±10 % for MasterPact MTZ1, 70 ms ±10 % for MTZ2, and 80 ms ±10 % for MTZ3. That spread matters for coordination studies where closing time affects arc-flash energy or sequence-of-event logging — use the figure for the specific frame in the assembly.
