Schneider Electric ComPact NSXm Molded Case Circuit Breaker, 4 Pole, 80A, 70kA Breaking Capacity, Clip-on, 690V AC LV426576

The Schneider Electric LV426576 ComPact NSXm Molded Case Circuit Breaker (MCCB) is designed for robust electrical protection and distribution in demanding industrial and commercial environments. With a four-pole configuration, it offers reliable isolation and fault protection for three-phase power systems, including the neutral conductor, making it especially suitable for panel boards, switchboards, and branch circuit applications.

This MCCB is rated for a maximum current of 80A, supporting high-capacity installations. Its substantial breaking capacity of 70kA at 380/415V delivers a high level of protection, capable of safely interrupting large fault currents typical in industrial settings. The LV426576’s advanced thermal magnetic tripping mechanism provides both overload and short-circuit protection, while Type D tripping characteristics ensure strong immunity to nuisance trips caused by equipment inrush currents.

Installation is straightforward via a clip-on mounting system, streamlining both panel assembly and maintenance. The breaker features robust screw terminals to facilitate secure and reliable cable connections. Engineered for flexibility, it accommodates operating voltages up to 690V AC, meeting the needs of many modern industrial electrical systems and providing ample headroom for future system upgrades.

The MCCB’s compact enclosure measures just 137mm in height, 108mm in width, and 80mm in depth, optimizing panel space while maintaining ease of use. The reset actuator features a toggle switch for intuitive manual operation and clear status indication. The Compact NSXm series is recognized for its adherence to major international standards (RoHS, IEC, EN, EAC, CE, CCC), ensuring safety and regulatory compliance across global projects.

Schneider Electric’s attention to construction quality is evident in the sturdy build and reliable operating mechanism, making this model suitable for harsh industrial locations where safety and uptime are paramount. This molded case circuit breaker is widely used in factory automation, utility panels, building infrastructure, electrical distribution boards, HVAC systems, and other applications where dependable protection and compact form factor are prioritized.

Summary of key benefits: four-pole design for three-phase protection, high 70kA breaking capacity, 80A rating, broad 690V AC voltage compatibility, reliable thermal magnetic tripping, and an easy-to-install clip-on mechanism. The LV426576 model from Schneider Electric delivers safety, durability, and performance for modern electrical power systems.
