Eaton Bussmann HRC Offset Tag Fuses - BS88 British Standard Fuses
Eaton Bussmann's offset tag fuses (or offset bolted tag fuses) are essentially a cylindrical fuse that is fitted with offset 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 measure. Eaton Bussmann's fuses are commonly found within a multitude of industrial and switchgear applications, electrical equipment, wiring systems and circuit breakers. This fuse range is suitable for general purpose use.
Features & Benefits
• The low-temperature rise enables the fuse to be suitable for high-density mounting
• Fuse links, specifically designed for the protection of equipment
• Conforms to industry standards
• Low voltage fuse
• High rupture capacity (HRC)
• Suitable for three-phase applications
• Suitable for type 2 co-ordinated applications as defined in IEC 947-4
• Low power loss, typically 20% lower than the requirements of BS 88

Why use a slotted tag fuse?
A slotted tag fuse is distinguished by the metal slotted tags that extend off the ends of the fuse. This tag can either enable the fuse to have an offset tag or be centred to the fuse. 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 within electrical circuits.

Eaton British Standard Fuse, A3, 100A OSD100
Use this low-voltage electrical fuse from the Eaton range to protect your equipment from current surges in industrial and commercial applications. This general-purpose component can be used for electrical systems that require fast responses to overcurrent and short circuits.
It acts as a weak link in the circuit, absorbing the damage that would otherwise have come to the system and instantly breaking the flow of current to it. A high-temperature tolerance allows the element in this fuse to melt without risk of explosion or electrical arcing.

Features & Benefits
• Current rating of 100A for use in heavy-duty applications
• Length of 95mm for standard installation
• Weight of 55.75g avoids adding strain to equipment
• Voltage rating of 550V AC (alternating current) for safe breaking without electrical arcs

Can I replace a fuse with a circuit breaker?
In some cases, yes. However, in critical upstream applications, a fuse is the necessary choice because it can withstand high fault levels without causing blackouts. A fuse also has a current-limiting feature that isn't found on a circuit breaker.
