Product details

Overview

The LV433882 is a Schneider MicroLogic 7.2 E electronic trip unit for the ComPact NSX250 frame, rated 250 A and wired for 4-pole (3 phases plus neutral left) distribution duty. It delivers LSIR protection — long-time, short-time, instantaneous, and earth-leakage — with adjustable long-time pickup from 100 to 250 A and short-time delay from 0 to 0.4 s.

The long-time pickup range (100 to 250 A) lets you set the trip unit to match the cable or load, not just the breaker frame. The short-time delay (0 to 0.4 s) gives selectivity headroom downstream — set it above the downstream breaker's clearing time.

Compared to the LV433806, which is a 100 A, 3-pole MicroLogic 7.2 E with a fixed long-time delay, the LV433882 carries 250 A on 4 poles with fully adjustable Tr and Tsd — the right choice when the panel requires 4-wire distribution and coordination flexibility.
