It carries the wiring for three circuits: PTE (push-to-trip), SDE2/RES (alarm/reset), and M2C/ESM (motor mechanism/energy status module). The block arrives pre-terminated, so it saves panel wiring time during breaker installation or swap-out. Mounts in the drawout cradle of MasterPact MTZ2 or MTZ3 frames. The three-wire harness connects the breaker's auxiliary and control circuits to the panel wiring without field-terminating each conductor. Rated for the wiring application only — it is the interconnection block, not a signal conditioner or relay interface.","metaTitle":"LV839491 MasterPact MTZ2/MTZ3 Pre-wired Terminal Block, Draw","metaDescription":"LV839491 is an active pre-wired terminal block for MasterPact MTZ2/MTZ3 drawout breakers. 3-wire chassis block with PTE+SDE2/RES+M2C/ESM.
