Three-pole operation provides synchronized protection across all phases, improving system reliability and reducing nuisance faults that can cascade through a line. This translates to fewer unplanned outages in critical applications such as conveyors and machine controls, keeping production lines running smoothly. The thermal-magnetic trip (T268) delivers precise fault sensing, enabling fast protection against overloads and short circuits and preserving motor life and downstream equipment. With a 50 kAIC short-circuit rating, this breaker supports high fault current conditions typical of large feeders, enhancing safety and system integrity. Front frame clamp mounting simplifies installation, reducing field labor and enabling reliable, repeatable assemblies in panel dress and distribution boards. An optional rocker lever adds convenient manual operation and status indication for quick, maintenance-friendly troubleshooting in industrial environments.
