It operates on a 12 VDC supply and is rated for control applications, providing a remote trip signal to open the breaker on command. The holding power consumption is 4.5 W, and the threshold tripping voltage range is 0.7 to 1.1 times the nominal voltage (Un) on opening. Maximum response time is 60 ms on opening a MasterPact MTZ1. The 12 VDC supply is the coil voltage — this release will not operate on AC or on a different DC voltage without an external converter. The 0.7 to 1.1 Un threshold means the release trips reliably when the supply drops to 8.4 VDC or rises to 13.2 VDC, but may not hold or trip outside that band. The 60 ms maximum response time governs how quickly the breaker opens after the trip signal is applied. For selectivity studies or arc-flash mitigation, that delay must be coordinated with upstream and downstream devices. Designed specifically for MasterPact MTZ1 drawout frames. The drawout mounting means the release is installed in the breaker cradle, not the moving portion — it stays wired when the breaker is racked out.","metaTitle":"Schneider Electric LV847449 MasterPact Shunt Trip Release, 1","metaDescription":"Schneider Electric LV847449 is an obsolete 2nd MX opening voltage release for MasterPact MTZ1 drawout breakers. 12 VDC supply, 60 ms response.
