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
• 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

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, A1 Size, 20A - Eaton Series - NITD20
Choose this British Standard fuse to protect circuitry and devices in your low-voltage electrical applications. Its a general-purpose component that effectively shields against short circuits and current overloads. The fuse acts as a self-wearing weak link, with a central wire that melts away if the current exceeds the circuit's capacity of 20A (amperes). This severs the connection and immediately stops the flow of electricity. Fuses like this are commonly used in industrial lighting and domestic applications.
Features & Benefits
• A1 style tags slot securely into your fuse holder thanks to the dual-pin blade design
• High breaking capacity of 80kA, so can safely stop a wide range of overcurrents
• Compact cylindrical fuse ensures low power loss, increasing the energy efficiency of your circuit
• High breaking capacity of 80kA, so can safely stop a wide range of overcurrents
• Compact cylindrical fuse ensures low power loss, increasing the energy efficiency of your circuit
Is this British Standard fuse suitable for Type 2 coordination?
Yes, this British standard fuse is suitable for Type 2 coordination applications. As it safely breaks the circuit without wider mechanical consequences, this fuse won't compromise the working of important motor control components after a short circuit fault.
