Schneider Electric WA4AAR63A3SFBFXXCX Circuit Breaker

Schneider Electric WA4AAR63A3SFBFXXCX Circuit Breaker (Square D) is a WA-series protective device equipped with a Micrologic trip unit that provides electronic overcurrent protection for electrical distribution panels. With a 63 A current rating, it is designed to interrupt fault currents in branch circuits to safeguard conductors, equipment, and enclosures from overloads and short circuits, while fitting Schneider Electric's WA family protection philosophy. The Micrologic trip unit embedded in this model delivers digital sensing and trip logic within the protection architecture, enabling coordinated operation with upstream devices and consistent protective performance across the panel. The WA4AAR63A3SFBFXXCX part number encodes the WA-series lineage and 63 A rating, aligning the device with Schneider Electric’s ecosystem of compatible enclosures, bus bars, and accessories, and it is intended for use in appropriate Schneider Electric panel boards and switchgear where electronic-trip protection is specified by the design; when selecting this breaker, practitioners typically verify voltage rating, breaking capacity, terminal size and mounting compatibility against Schneider Electric WA-series catalogs and local electrical codes to ensure proper fit and safe operation.
