Overview
The LV433965 is a MicroLogic 7.3 E AL electronic trip unit for the Schneider ComPact NSX400 and NSX630 molded-case circuit breakers, rated 400 A with 3 poles and built for distribution duty. It provides LSI protection (long-time, short-time, instantaneous) with an adjustable long-time pickup range of 160 to 400 A and an integrated earth-leakage function, all monitored through an LCD display.
How it compares
Compared to the LV433808, which is a 4-pole trip unit rated 250 A with a fixed long-time delay, the LV433965 is a 3-pole unit rated 400 A with an adjustable Tr. Pick the LV433965 for 3-pole distribution panels needing higher ampacity and field-adjustable overload timing; choose the LV433808 when the BOM requires 4-pole switching at 250 A.
Lifecycle and sourcing
The LV433965 is in active production; lead time is confirmed per RFQ for the exact build code.
