The Schneider LV848490 is an MX opening voltage release for MasterPact MTZ2 and MTZ3 drawout circuit breakers. It operates on a 12 VDC supply with a holding power consumption of 4.5 W, and its maximum response time is 60 ms on opening. This is a standard control-type voltage release, designed for the MasterPact range, and its device application is control. The circuit breaker mounting mode is drawout, meaning this release integrates into the breaker's drawout chassis.
Integration Note
The MX release mounts directly into the drawout cradle of a MasterPact MTZ2 or MTZ3 breaker. The 12 VDC coil holds at 4.5 W; verify the control voltage is within the 0.7 to 1.1 Un trip threshold range to avoid nuisance opening. The 60 ms response time is the maximum mechanical opening time — the breaker's arc-extinction time adds to the total fault clearance interval.
