Eaton BAF-3 Fuse - Fast-Acting, 3 A, CE Marked
Part Number: BAF-3
Quick Summary
The Eaton BAF-3 fuse provides fast-acting protection for 3 A circuits in control panels and industrial electronics. Sourcing a compact, reliable fuse that fits ferrule-end connections and delivers predictable interrupt behavior can be challenging in dense panels. This device carries CE Marked compliance, aligning with EU safety requirements and supporting regulatory acceptance across many markets, while offering robust nickel-plated endcaps and a standard 250 V rating for durable performance in varying environments. By leveraging this Bussmann series fuse, engineers can reduce footprint, simplify stocking, and lower panel wiring complexity while maintaining clear protection parameters. In practice, its ferrule-end construction and non-indicating design streamline installation and maintenance, delivering consistent protection without ambiguity during fault tracing.

Datasheet - FNQ-30
Feature → Business Impact → Application: The BAF-3 is a 3 A fast-acting fuse rated for 250 V with interrupt ratings of 10 kAIC at 125 Vac and 100 AIC at 250 Vac. Business impact: quick fault clearing protects sensitive loads, minimizes downtime, and reduces secondary damage to adjacent components. Application: ideal for control panels and small automation circuits where space is at a premium. Feature → Business Impact → Application: Ferrule-end x ferrule-end connections with nickel-plated endcaps provide corrosion resistance and reliable contact over time. Business impact: longer service life, lower maintenance, and consistent performance in harsh environments. Application: retrofit and new installs in industrial automation lines. Feature → Business Impact → Application: Compact form factor at 1.5 in length and 0.41 in width/height enables dense panel layouts. Business impact: saves panel real estate, simplifies wiring, and accelerates field replacements. Application: compact control cabinets and machine enclosures. Feature → Business Impact → Application: Non-indicating fuse design reduces wiring complexity and eliminates misleading presence indicators. Business impact: faster fault diagnosis and cleaner schematics. Application: electrical protection in automated systems without indicator noise. Feature → Business Impact → Application: CE Marked compliance supports cross-border deployment and regulatory alignment. Business impact: smoother procurement, less qualification effort, and broader market access. Application: multinational factories and regulated environments. Feature → Business Impact → Application: Silver-plated fuse caps (special feature) improve contact reliability and reduce resistance at connection points. Business impact: improved performance under cycling loads and extended lifecycle. Application: high-cycle control panels and equipment with frequent on/off cycles.

FAQs
Install the BAF-3 by inserting it into ferrule-end fuse holders designed for Bussmann midget fuses. The device length is 1.5 in with 0.41 in width and height, and the ferrule-end connections ensure secure, corrosion-resistant contact with nickel-plated endcaps. Confirm panel cutouts match the 1.5 in depth and verify the 250 V rating for your circuit.
The BAF-3 is a 3 A fast-acting fuse rated for 250 V. It provides 10 kAIC at 125 Vac and 100 AIC at 250 Vac, making it suitable for protecting small loads in control panels and automated equipment. It is non-indicating and ships in standard packaging, simplifying procurement and replacement.
Yes. With a 3 A rating and 250 V operating limit, the BAF-3 is well-suited to protect control circuits in automation panels and small machines. Its ferrule-end design, nickel-plated endcaps, and non-indicating nature reduce installation complexity and improve reliability in compact enclosures while providing clear, predictable fault clearing.
The BAF-3 is CE Marked, aligning with European safety requirements and facilitating compliance in many international markets. While CE is the primary certification listed, users should verify region-specific standards as needed. The fuse’s standard 250 V rating and robust construction support reliable performance in CE-regulated environments.
The BAF-3 is a non-indicating fuse with nickel-plated endcaps and ferrule-end connections, designed for durable service in industrial panels. Replacement is straightforward due to its standard Bussmann form factor. The compact 1.5 in length saves panel space, while the reliable interrupt ratings reduce nuisance outages and lower total cost of ownership over the machine lifecycle.
