It operates on a 277 V AC 50/60 Hz control circuit and triggers the breaker trip mechanism when the control voltage drops to between 0.7 and 1.1 times the rated Un. The drawout mounting mode means this release plugs into the MasterPact MTZ cradle, not the fixed version — verify your breaker frame is a drawout MTZ1, MTZ2, or MTZ3 before ordering. The 50 ms ±10% response time is consistent across all three MTZ frame sizes, so the trip delay is predictable regardless of frame rating. The 277 V AC control circuit is a single-voltage variant; if your panel control voltage is 240 V or 480 V, this release will not operate correctly. Supply holding power is 4.5 W / 4.5 VA, a modest load on the control transformer.","metaTitle":"Schneider Electric LV839230 MX communicating opening voltage","metaDescription":"Obsolete MX communicating opening voltage release for MasterPact MTZ drawout breakers. 277 V AC control circuit, 50 ms response.
