MX com Opening Coil for MasterPact MTZ Drawout
The LV839226 is a communicating opening voltage release (MX com) for Schneider Electric MasterPact MTZ drawout circuit breakers. Control voltage is 24 V AC 50/60 Hz or 24...30 V DC, with a tripping threshold of 0.7...1.1 Un. Holding power is 4.5 VA / 4.5 W. Response time is 50 ms ±10% across the MTZ1, MTZ2, and MTZ3 frame sizes.
Drawout Mounting — What It Means for Fit
Drawout mounting means this coil installs into the breaker's accessory compartment without removing the breaker from the cradle. It's wired through the secondary disconnect terminals, so the control circuit stays connected when the breaker is racked to the test or disconnected position. This is the standard fit for MasterPact MTZ drawout frames — not for the fixed-mount version.
Lifecycle Status — Obsolete, Sourced to Order
Schneider Electric lists the LV839226 as obsolete.
