MX opening voltage release, fixed MasterPacT MTZ1/MTZ2 Active, 380-480 V AC.
Description
About the MX
About the MX
The Schneider Electric LV947365 is an MX opening coil for fixed MasterPacT MTZ1 and MTZ2 Active circuit breakers fitted with the MicroLogic Active control unit, supplied for 380-480 V AC 50/60 Hz only. Energizing the coil trips the breaker open within 60 ms once voltage reaches 0.7-1.1 Un. It is sold as a single piece with an instruction sheet for installation.
Selection Notes
The LV947365 is the AC-only, 380-480 V top of the MX opening-coil range, while the 100-130 V and 200-250 V siblings also accept DC supply; confirm the shunt-trip source is AC before ordering it. Like the rest of the MX family it is limited to MTZ1 and MTZ2 Active frames. The 0.7-1.1 Un trip window and 60 ms response time are unchanged from the lower-voltage variants. It ships one piece per package, matching the rest of the MasterPacT Active MX coil family.
