The threshold tripping voltage spans 0.7 to 1.1 Un, and the response time is 50 ms ±10% across the MTZ1, MTZ2, and MTZ3 frames. The LV839244 uses a drawout mounting mode, meaning it plugs into the breaker cradle rather than being hard-wired. This allows the opening coil to be swapped without removing the MasterPact MTZ from the switchgear — useful for retrofit or maintenance on drawout chassis.","metaTitle":"Schneider Electric LV839244 MX 2nd Opening Voltage Release,","metaDescription":"LV839244 is an obsolete MX 2nd opening voltage release for MasterPact MTZ drawout breakers. 277 V AC control circuit, 50 ms response time.
