The LV839480 is a pre-wired terminal block for MasterPact MTZ2 and MTZ3 drawout circuit breakers. It carries three wires and integrates PTE+SDE2/RES plus eight OF auxiliary contacts — the full signal complement for remote status and trip indication on a drawout chassis.
The terminal block is designed for the drawout cradle of MasterPact MTZ2 and MTZ3 frames. It replaces or supplements the factory wiring harness when additional OF contacts or the PTE (trip indicator) and SDE2 (fault-signal) outputs are needed for a panel's control wiring. The 3-wire configuration covers the basic power and signal routing through the cradle's disconnect plug.
