It is designed for MasterPact MTZ2 and MTZ3 drawout circuit breakers, providing a controlled opening function on a 12 VDC supply. The device signals electrical push-button activation, coil powered, error, and ready-to-close-or-open states. Its maximum response time is 60 ms on opening for both MTZ2 and MTZ3 frames, and holding power consumption is 4.5 W. The tripping voltage threshold is 0.7 to 1.1 times the rated supply voltage (Un) on opening, meaning it will reliably release when the control voltage drops to 8.4 VDC or rises to 13.2 VDC. No official replacement part is documented, so any substitution must be validated against the specific MasterPact frame and control scheme. ## Deployment context The LV848457 mounts in the drawout cradle of a MasterPact MTZ2 or MTZ3 breaker. This is a panel-integrated component, not a standalone device — it communicates with the breaker's control unit and provides diagnostic feedback via its signalling outputs. The communicating control type means it interfaces with the breaker's communication network, allowing remote status monitoring and trip diagnostics. This is typical for power distribution in industrial plants, data centers, and commercial buildings where breaker status needs to be visible to a BMS or SCADA system.","metaTitle":"Schneider LV848457 MasterPact MX Opening Voltage Release, 12","metaDescription":"Schneider Electric LV848457 MX opening voltage release for MasterPact MTZ2/3 drawout breakers. 12 VDC, 60 ms response, 4.5 W hold.
