It monitors the control voltage and trips the breaker when voltage drops below 0.35 to 0.7 Un, preventing the breaker from closing until voltage returns above 0.85 Un. The 'diagnostic' variant adds a signaling function: it reports coil-powered-open and error states, which is useful for remote monitoring in safety circuits. ## Lifecycle Status and Sourcing Reality Schneider Electric has marked the LV839267 as obsolete. No official successor order code is listed.","metaTitle":"Schneider Electric LV839267 MN Diagnostic Undervoltage Relea","metaDescription":"Schneider Electric LV839267 MN diagnostic undervoltage release for MasterPact MTZ drawout. 100-130 V AC/DC control voltage.
