100 A amperage rating with 240 V operation and neutral-enabled wiring ensures robust overload protection and straightforward integration with standard panel architectures. This minimizes miswiring risks and reduces panel redesign costs. It is well suited for motor control centers, conveyors, and process lines in manufacturing environments where uptime matters. The enclosure is a NEMA 3R rated, painted galvanized steel housing that delivers reliable protection against rain, dust, and corrosion. This means safer outdoor and rugged indoor installations, fewer weather-related faults, and longer service life. Fuse class provision with Class H fuses and neutral configuration enables selective coordination and fast fault isolation. This reduces downtime, protects downstream equipment, and simplifies stocking by using common fuse types. HP rating flexibility supports scalable motor control for mixed loads, offering up to 7.5 hp on single-phase and higher ratings on three-phase installations when paired with appropriate fusing and time-delay characteristics. Installer-friendly dimensions and weight support quick deployment in tight spaces; 22.5 in depth, 12.75 in width, 9 in height, and a 26 lb weight align with common electrical footprints and reduce labor time. UL Listed certification provides regulatory assurance for safety-critical installations, while the warranty of one year from installation or eighteen months from shipment supports cost of ownership and service planning.
