Product details

Overview

The LV431150 is a Schneider ComPact NSX250B molded case circuit breaker rated 250 A continuous with a 15 kA breaking capacity at 415 V AC, carrying a MicroLogic 2.2 electronic trip unit for L, So, and I protection. It is a 4-pole fixed-mount unit on a 690 V AC supply, built to EN/IEC 60947, with a Class II insulation rating and 8 kV impulse withstand.

The LV431150 carries 4 poles at 250 A and 15 kA breaking capacity, whereas the 2-pole LV438709 is rated 160 A and 5 kA — the LV431150 handles higher current and fault levels, and its 4-pole design suits three-phase-plus-neutral distribution panels that the 2-pole LV438709 cannot serve without rewiring.

The LV431150 is in active production; lead time is confirmed via RFQ for the exact build code.
