It is a control voltage release that trips the breaker on loss or application of control voltage, with a threshold tripping voltage of 0.7...1.1 Un. Control circuit voltage is 48 V AC 50/60 Hz or 48...60 V DC, with a supply holding power of 4.5 VA / 4.5 W. Response time is 50 ms ±10% across MasterPact MTZ1, MTZ2, and MTZ3 frames. Schneider Electric has classified the LV839227 as obsolete. ## Deployment context This MX coil mounts in the drawout cradle of MasterPact MTZ breakers — the drawout mechanism allows the breaker to be racked out for maintenance without disturbing the control wiring. It is a control-voltage trip accessory, not a standalone device; install it in the breaker's accessory slot per the MTZ wiring diagram.","metaTitle":"Schneider Electric LV839227 MX Opening Coil, 48 V AC/DC, Dra","metaDescription":"Obsolete MX communicating opening voltage release for MasterPact MTZ drawout breakers. 48 V AC 50/60 Hz, 48-60 V DC.
