Eaton Bussmann BAF-2 2A 250V Fast-Acting Supplemental Fuse

Buy Eaton Bussmann BAF-2 fuse online.The Eaton Bussmann BAF-2 is a 2 amp, 250Vac fast-acting supplemental midget fuse designed for general-purpose circuits, lighting circuit protection, meter circuits and other compatible electrical equipment applications.

Featuring a compact 13/32 inch × 1-1/2 inch cylindrical format, the BAF-2 uses ferrule connections at both ends for installation in compatible midget fuse blocks, holders and fuse clips. Its fast-acting response is intended for applications that require prompt interruption of overcurrent without an intentional time delay.

Technical Specifications

Typical Applications

• General-purpose electrical circuits
• Lighting circuit protection
• Meter circuits
• Instrumentation circuits
• Control equipment requiring supplemental protection
• Replacement applications that specifically specify BAF-2

Fast-Acting Overcurrent Protection

The Bussmann BAF-2 uses a fast-acting operating characteristic. Unlike a time-delay fuse, it does not intentionally tolerate extended startup or inrush currents before opening.

This operating response makes the BAF-2 suitable for compatible general-purpose, lighting and meter circuits where the equipment manufacturer specifies a fast-acting supplemental fuse.

Supplemental Fuse Classification

The BAF-2 is a supplemental fuse intended for use inside equipment or in applications where supplemental overcurrent protection is permitted. It should not be treated as a Class CC or other branch-circuit fuse.

A supplemental fuse must not be used as a substitute where the electrical system requires a branch-circuit-rated overcurrent protective device. Always verify the equipment documentation and applicable electrical requirements before installation.

Important Interrupting-Rating Information

The BAF-2 has a published interrupting rating of 100 A at 250 Vac and 10 kA at 125 Vac. The interrupting rating changes with the applied system voltage and should not be interpreted as 10 kA at 250 Vac.

Before ordering or installing this fuse, confirm that the system voltage and available fault current remain within the published ratings of both the fuse and the installed fuse holder.

Compact Midget Fuse Format

The BAF-2 uses the common 13/32 inch × 1-1/2 inch midget fuse format. Its ferrule terminals allow installation in compatible modular fuse blocks, DIN-rail holders, panel-mount holders, in-line holders and approved fuse clips.

Physical fit alone does not confirm electrical compatibility. Current rating, voltage rating, operating characteristic, fuse classification and interrupting rating must all match the application.

Compatible Fuse Blocks and Holders

Compatible Bussmann holder families for BAF supplemental midget fuses include BMM modular fuse blocks, CHM DIN-rail holders, HPM and HPS panel-mount holders, HEB and HEX in-line holders, and compatible PCB fuse clips.

The exact holder catalog number depends on pole count, mounting method, terminal configuration and required electrical ratings. Confirm the complete holder specification before installation.

BAF-2 Is Not a Class CC Fuse

The BAF-2 is a 2A, 250Vac fast-acting supplemental midget fuse. It should not be described or marketed as a Class CC, rejection-style or current-limiting branch-circuit fuse.

Other fuse families may have similar physical dimensions but different voltage, interrupting and application ratings. Always verify the complete catalog number printed on the original fuse or specified by the equipment manufacturer.

Certifications and Compliance

• CSA Certified at 250 Vac
• CE marked

The 2A BAF-2 rating is not included in the BAF series UL Listed range. Eaton lists UL certification for BAF ratings from 3A through 15A.

Important Selection Information

Before purchasing, confirm the complete manufacturer catalog number BAF-2, the required 2 amp rating, the 250Vac maximum voltage rating, the applicable interrupting rating and compatibility with the installed fuse holder.

Do not select a replacement fuse solely by amperage, appearance or physical dimensions. The operating speed, voltage rating, fuse classification, interrupting rating and certification requirements must also be verified.

Ordering Information

Order using the complete manufacturer part number Eaton Bussmann BAF-2. Confirm the required quantity, product condition and all electrical specifications before purchase or installation.
