Product details

The Schneider LV839245 is an MX second opening voltage release for MasterPact MTZ drawout circuit breakers. It serves as a shunt trip — a remote-opening coil that drops the breaker on command from a control signal or protection relay. Control circuit voltage is 380/480 V AC 50/60 Hz or 380/480 V DC, so it ties directly into a 400 V class control bus without an intermediate transformer.

Drawout mounting means this coil installs into the breaker cradle, not the fixed base. Response time is 50 ms across MTZ1, MTZ2, and MTZ3 frames. Holding power is 4.5 W / 4.5 VA. Trip threshold spans 0.7...1.1 Un.

Installation context

This component mounts inside the MasterPact MTZ drawout cassette. Control voltage is 380/480 V AC/DC. Response time is 50 ms.

Frequently asked questions

What MasterPact frames does this coil fit?

The 50 ms response time is specified for MTZ1, MTZ2, and MTZ3 drawout frames. One coil covers the entire MTZ drawout family. Mounting is drawout type, meaning it installs in the breaker cassette.
