The LV836389 is a ULP port module with internal wiring, designed specifically for Schneider Electric MTZ2 and MTZ3 air circuit breakers. It provides the communication interface between the breaker's internal systems and the ULP (Universal Logic Plug) network, enabling remote monitoring and control through the breaker's control unit.
Integration Note
Internal wiring variant means the module connects directly to the breaker's internal bus without an external cable harness. Mounts inside the MTZ2/MTZ3 chassis — no additional DIN-rail space required. Verify the control unit firmware revision supports this port module before commissioning.
