Schneider Electric LV431831 Compact Circuit Breaker

Schneider Electric LV431831 is a ComPact NSX250N molded-case circuit breaker designed for three‑phase distribution in industrial and commercial panels. It pairs an NSX250N frame with a TM200D (TMD) trip unit set for 200 A, delivering thermal‑magnetic protection with long‑time and instantaneous tripping for overloads and short circuits. Rated for 415 VAC, it provides a 50 kA short‑circuit breaking capacity at that voltage and comes in a 3‑pole configuration to protect all three phases. As part of the NSX ComPact family, LV431831 is intended for use in switchboards and panelboards where compact protection is required without sacrificing interrupting capability, making it suitable for feeders to motors, transformers, and other heavy loads in industrial environments. The TM200D/TMD trip unit enables coordinated protection within Schneider’s NSX lineup, offering reliable disconnection when faults occur while maintaining stable operation under normal load conditions.
