- Description
The Schneider Electric LV847383 is an MN instantaneous undervoltage release for fixed MasterPact MTZ1, MTZ2, and MTZ3 air circuit breakers, supplied for 200-250 V AC 50/60 Hz or 200-250 V DC control circuits. It opens the breaker automatically once the supervised voltage falls to 0.35-0.7 Un, then re-closes the circuit once voltage recovers to 0.85 Un.

Selection Notes
Choose the LV847383 when the supervised control circuit runs at 200-250 V AC or DC rather than the 100-130 V or 380-480 V bands covered by the other MN variants in this family; the release will not trip correctly if it is fitted to the wrong voltage band. Like the rest of the MN range it mounts only on fixed MTZ1, MTZ2, and MTZ3 breakers. The 45 ms response on MTZ1 and 95 ms on MTZ2/MTZ3 should be factored in when the release is part of a wider safety interlock chain.
