Schneider Electric LV436081 Molded Case Circuit Breaker

The LV436081 Micrologic 5.3E trip unit is Schneider Electric’s electronic protection module designed for PowerPact L-frame molded‑case circuit breakers, specifically compatible with NSJ400/600 models in a 400 A, 3-pole configuration. As an electronic trip unit, Micrologic 5.3E provides the protective logic for overload and short‑circuit events and is intended to be installed in 400 A NSJ series breakers to upgrade protection capabilities in existing panels. This trip unit is built for industrial power distribution applications where reliable 400 A protection is required, such as feeders, motor control centers, and distribution boards, enabling precise coordination within the NSJ400/600 frame. Its plug‑in form factor supports straightforward replacement or upgrade, allowing plants to modernize protection without replacing the entire MCCB.
