Bussmann series Class H (K) Fuses Data Sheet no. 1030
Feature: Amperage rating of 350 A. Business impact: Supports robust protection for high-load circuits, reducing the risk of nuisance trips and equipment damage. Application: Main feeders and protective circuits in industrial panels. The 350 A rating translates to predictable coordination with upstream protection, enabling reliable uptime in manufacturing lines. Feature: Interrupt rating of 10 kAIC at 250 VAC. Business impact: Withstands high fault currents to minimize collateral damage and cascading failures. Application: Control cabinets and power distribution where fault currents can spike, improving safety margins and reducing downtime. This specification helps engineers design protection schemes with clear clearance paths and compliance with electrical codes. Feature: Non-current-limiting construction. Business impact: Simplifies protection strategy when precise current limitation is not required, enabling consistent fuse clearing characteristics. Application: General purpose protection in legacy and new equipment where non-current-limiting behavior is preferred for system stability. Feature: Class H, non-indicating Bussmann series fuse. Business impact: Familiar form factor with predictable replacement behavior, reducing commissioning time and part mis-selection. Application: Standardized protection across multiple panels, improving procurement efficiency and stocking accuracy. Feature: One-time fuse. Business impact: Clear lifecycle behavior minimizes wear while providing definitive protection; simplifies warranty and maintenance planning. Application: Critical equipment where a single protective action is expected before replacement. Feature: CE Marked compliance. Business impact: Supports regulatory alignment in European markets and global deployments requiring CE certification. Application: Industrial automation projects with strict compliance requirements, ensuring fast qualification and audit readiness. Feature: Packaging type and quantity. Business impact: Standard packaging and single-unit quantity streamline inventory management and reorder processes. Application: Field service and OEM assembly lines where fast replacements are essential to keep machines running.

FAQs
The NON-350 is a Class H, non-current-limiting, one-time fuse rated at 350 A and 250 V, CE marked. Ensure it is used within panels designed for Bussmann Class H fuses and that the form factor (8.63 in length, 2.06 in height and width) fits the enclosure footprint. Plan for straightforward replacement with a single unit per fault event to minimize downtime.
Key specs are a 350 A amperage rating and a 10 kAIC interrupt rating at 250 VAC. These figures define the maximum current the fuse can carry and the fault current it can interrupt without damage. In design terms, they support reliable protection for high-load circuits while ensuring safe interruption of faults up to 10 kA at standard industrial voltages.
The NON-350 is a general-purpose, non-current-limiting fuse with a high interrupt rating ideal for broad protection roles. For motor circuits, assess starting inrush, circuit configuration, and coordination with upstream protection. If precise motor inrush handling is required, pair this fuse with appropriate protective schemes or consider a device with current-limiting features where applicable.
The NON-350 is CE marked, indicating conformity with European health, safety, and environmental directives. While other certifications are not listed for this specific part, CE marking ensures market eligibility in Europe and supports regulatory acceptance in global projects that reference CE compliance as a baseline for equipment protection components.
Being a one-time, non-current-limiting fuse, the NON-350 provides predictable replacement cycles and simple inventory management—one part per protection point. This reduces maintenance complexity and stocking variability. The fuse’s standard dimensions and packaging streamline field replacements, minimizing downtime and total cost of ownership in routine protection schemes.
