APC 0M-3391 NH2 Style Fuse 400 A | Power Distribution

Protect critical power distribution with a 400 A NH2 style fuse assembly engineered for high-current fault isolation. In dense electrical environments, the right fuse is not just a consumable — it is a control point that helps limit damage, preserve downstream equipment, and keep maintenance predictable. APC identifies this assembly as a dedicated NH2 style fuse component, making it suitable for systems that require a defined high-amperage protection element rather than generic replacement hardware. That matters in infrastructure where electrical coordination, serviceability, and consistent protection behavior are part of the operating standard. For procurement teams and facility engineers, this type of component helps maintain continuity in power distribution assemblies while supporting planned replacement cycles. It is a practical choice when the application calls for a 400 A fuse format aligned to existing NH2 style infrastructure. When uptime, fault containment, and equipment protection are on the line, the specification itself is the value.
