Bussmann series Class H (K) Fuses Data Sheet no. 1030
Feature: Non-indicating general-purpose NOS fuse with 2 A rating. Business impact: Simplified protection for routine control circuits without over-triggering on standard inrush. Application: Control panels, machine wiring, and automation circuits where precise current limiting is not required. Feature: 50 kAIC interrupt rating at 600 Vac. Business impact: High fault tolerance protects upstream equipment and minimizes collateral damage during short circuits. Application: Motor starters, power feeds, and high-current branch circuits in manufacturing lines. Feature: Class H fuse family with pin-indicating capability. Business impact: Quick identification of blown fuses reduces downtime and speeds maintenance in busy control cabinets. Application: Routine replacement in automation panels and field service scenarios. Feature: Standard packaging and 10‑per-box quantity. Business impact: Optimized stocking and faster replenishment for OEMs and maintenance teams, lowering logistics costs. Application: Batch purchases for panel builders and service providers. Feature: CE Marked and RoHS-friendly. Business impact: Ensures regulatory alignment across global installations, easing audits and compliance reporting. Application: Global deployments of control systems and electrical protection schemes. Objection handling: While NOS-2 is non-current-limiting, it provides reliable protection for general circuits with predictable clearing behavior, making it suitable where current limiting is not a requirement. For applications needing fast response to inrush, a current-limiting alternative may be explored within the Bussmann Class H family.

FAQs
NOS-2 is designed as a Bussmann Series Class H (K) fuse intended for standard fuse holders used in general control panels. It ships in standard packaging (10 pieces per box) and aligns with typical panel layouts and the Class H footprint, ensuring straightforward installation and swapping during maintenance.
NOS-2 is a 2 A, non-current-limiting fuse with a 50 kAIC interrupt rating at 600 Vac and a voltage rating of 600 V. These specs support reliable fault clearance for general-purpose circuits without excessive nuisance trips in standard automation panels.
NOS-2 is well-suited for control panels, general-purpose branch circuits, and automation equipment where a 2 A protection level is appropriate and full interruption capability up to 50 kAIC is required, especially in non-inrush-sensitive applications.
NOS-2 carries CE Marking and is RoHS-ready via Eaton’s RoHS tool, supporting global compliance and streamlined audits for electrical installations across regions.
With pin-indicating integrity features and a compact 0.81 in by 0.81 in footprint, NOS-2 facilitates quick fuse identification and replacement, reducing downtime. The high 50 kAIC rating also mitigates downstream damage during faults, contributing to longer equipment life and lower maintenance costs.
