The signalling function reports coil-powered error and MN-open status, so the control system knows the release state. Control voltage is 24 V AC at 50/60 Hz or 24...30 V DC. The undervoltage release trips between 0.35 and 0.7 Un on opening and closes at 0.85 Un. Holding power draw is 4.5 VA / 4.5 W. Response time is 40 ms ±5% for MasterPact MTZ1, and 90 ms ±5% for MTZ2 and MTZ3 frames. The communicating control type means it integrates with the breaker's digital communication bus for status and diagnostics. Schneider Electric has classified the LV839265 as obsolete. ## Deployment context This release mounts in the drawout cradle of a MasterPact MTZ air circuit breaker. The drawout form factor means the release can be swapped without removing the breaker from the switchgear — useful for panel maintenance and fault isolation in industrial power distribution.","metaTitle":"Schneider Electric LV839265 MN Diagnostic Undervoltage Relea","metaDescription":"LV839265 MN diagnostic undervoltage release for MasterPact MTZ drawout. 24 V AC/DC, safety-rated.
