Enhanced visible blades provide quick status verification, reducing operation errors and service time. This translates to safer hand-offs and faster maintenance in busy plant environments, particularly within motor control centers and power distribution panels. The 400 A amperage rating and 600 V max enable protection of large feeders and motor loads, delivering reliable protection and minimizing nuisance trips in high-demand applications such as press lines or extrusion lines. Fuse class provision with Class H fuses offers protective coordination with upstream devices, supporting dependable shutoff during fault conditions and reducing collateral damage during faults in complex conveyor systems. Fusible without neutral simplifies wiring and stock management, enabling faster installation and lower installation costs on complex three-phase feeders. The NEMA 12, NEMA 3R enclosure and painted galvanized steel construction deliver rugged environmental protection, making installations in dusty plants, portable trailers, and protected outdoor spaces practical. Dimensions and weight align with standard control cabinet footprints, allowing straightforward retrofit into existing layouts and minimizing disruption during upgrades. UL Listed certification reinforces procurement confidence and regulatory compliance across industrial projects.
