The LV839485 is a pre-wired terminal block assembly from the MasterPact MTZ2 and MasterPact MTZ3 range, designed for drawout circuit breaker installations. It serves as the chassis terminal block set for the PTE (power transfer equipment) and M2C-ESM (energy sensor module) options on these frames.
Integration context
This terminal block is specific to drawout-mounted MasterPact MTZ2 and MTZ3 breakers. It pre-wires the chassis connections for the PTE and M2C-ESM options, so the block stays in the cradle when the breaker is racked out. Verify the cradle depth and wiring routing against the existing panel layout before ordering — the block occupies the space behind the breaker mounting plate.
