Eaton Bussmann Series Bolted Tag Fuse - Fast Acting (FF) HRC Power Fuse Range
Eaton Bussmann Series bolted tag fuse is essentially a fuse that is fitted with brackets, these brackets allow the fuse to be bolted onto a fuse holder. Predominantly this type of fuse is used within installations as a "weak link". They are designed to break when a fault occurs, such as an overcurrent or short circuit - they are a safety and damage protection measure. Cooper Bussman's fuses are commonly found within a multitude of industrial applications, electrical equipment and wiring systems.

Eaton British Standard Fuse, 250A Current Rating, 690V AC / 500V DC Voltage Rating 250FM
This British Standard fuse from Eaton offers protection for components such as power inverters and convertors in your electrical circuit. Its FF speed indicates that it's a very fast-acting fuse, so it'll blow quickly in the event of a short circuit to interrupt the power before any damage can be suffered. As a high rupture capacity (HRC) device, it's capable of stopping a fault current that's much higher than the circuit's normal operating current.
Features & Benefits
• Offset bolted tags are compatible with many industrial distribution panels and let make a secure connection
• Compact size of 38 (diameter) x 50 (length) x 41mm (height) minimises power use and heat loss
• Compact size of 38 (diameter) x 50 (length) x 41mm (height) minimises power use and heat loss
Can I use this fuse to protect a semiconductor?
Yes – the aR (accompanied semiconductor protection) class means it's suitable for protecting applications such as rectifiers and reduced-voltage starter motors.
What's different about a semiconductor fuse?
Semiconductor fuses, also known as aR type fuses, are very fast-acting with low melting integral values and peak let-through currents. They offer short-circuit protection only and must not be used as a replacement for a gR class fuse, which also handles overloads.
