Feature: 400 A amperage rating and three-pole LG frame deliver robust protection for large feeders and motor connections. Business Impact: Higher current handling reduces the risk of nuisance trips and minimizes the need for oversized protection devices, lowering total cost of ownership. Application: Suitable for power distribution panels and motor control centers in manufacturing and process industries, where reliable protection is critical for uptime. Feature: 65 kAIC interrupt rating at 240 Vac, 35 kAIC at 480 Vac, and 18 kAIC at 600 Vac. Business Impact: Scalable short-circuit protection across line voltages, enabling standardized protection schemes while meeting international standards. Application: Ideal for facilities with mixed-voltage equipment and panel designs that require consistent coordination with upstream protection. Feature: Shunt trip option 12-24 Vac/dc on the left terminal, same side. Business Impact: Enables remote tripping for centralized control rooms and safety interlocks. Application: PLC-controlled shutdowns and emergency interlock schemes across process lines. Feature: 50/60 Hz operation and 80% rated. Business Impact: Aligns with typical industrial power systems and reduces derating concerns, simplifying panel design. Application: Suitable for facilities connected to global utility grids and variable loads. Feature: Certifications UL Listed, CSA Certified, IEC Rated, CE Marked; HACR rated. Business Impact: Regulatory compliance across geographies, supporting global OEM deployment and service support. Application: OEM panels, control centers, and field-installable protection schemes that require recognized standards. Feature: Compact footprint and weight—4.09 in depth, 5.48 in height, 5.48 in width, 15 lb. Business Impact: Easier installation in tight panels and streamlined field retrofits, reducing assembly time and labor costs. Application: Panel builders and integrators upgrading legacy MCCBs in space-constrained environments.
