Schneider Electric LV429551 Adjustable Circuit Breaker

Schneider Electric LV429551 is a three-pole Compact NSX100B molded-case circuit breaker (MCCB) with a TM80D trip unit, delivering adjustable overload protection in the 56 A to 80 A range and a 25 kA short-circuit breaking capacity at 415 VAC. Rated for 415 VAC operation at 50/60 Hz, it is designed for industrial distribution panels requiring reliable branch-circuit protection for 3‑phase networks. The 80 A nominal rating can be scaled down within the 56–80 A window to match the protected load, while the TM80D mechanism provides coordinated thermal and magnetic tripping to respond to overloads and faults. As part of Schneider Electric's Compact NSX family, LV429551 emphasizes a compact footprint without sacrificing protection performance, making it suitable for space‑constrained panels and equipment enclosures. Typical applications include industrial control panels and distribution boards where configurable overcurrent protection and fast fault interruption are required to safeguard wiring and downstream devices. The LV429551 designation identifies a 3‑pole NSX100B unit configured for TM80D, with a 25 kA short‑circuit rating at 415 VAC, aligning with Schneider Electric's specifications for this series.
