Tag fuses are critical safety components used to interrupt excessive electrical currents, thereby protecting equipment and wiring from damage. Commonly employed across industrial settings, these fuses feature metal tags that facilitate secure mounting within fuse holders. Available in a variety of configurations — such as bolted, centred, offset, and slotted — tag fuses are suitable for diverse operational requirements.
Tag fuses function by incorporating a fusible element that melts when the electrical current exceeds a predefined threshold. This action breaks the circuit, effectively halting the current flow and protecting downstream components. The metal tags at either end of the fuse ensure a stable mechanical and electrical connection within the fuse holder.
Tag fuses are available in several configurations, each suited to specific installation and performance requirements. The main types include:
Also referred to as bolted fuses or bolt type fuses, these cylindrical fuses include solid tags or brackets at both ends, allowing them to be bolted securely into position. Bolted tag fuses are available in various current ratings, including popular options such as 50 amp bolt on fuse and 60 amp bolt on fuse models. For applications requiring high fault current interruption, a bolted type HRC fuse is often the preferred choice.
Centred tag fuses feature a central tag on each end, typically within a square or rectangular housing. They are commonly used in open fuse bases and allow for straightforward replacement and maintenance.
Offset tag fuses are characterised by asymmetrically positioned tags on a cylindrical body. This design provides flexibility in installation, particularly where space constraints or specific fuse holder designs are involved. Both solid and slotted tags are available in this configuration.
These fuses incorporate slotted terminals, which may be aligned either straight or offset. Slotted tag fuses support versatile mounting options and are well-suited to industrial applications requiring secure connections and easy removal.
HRC fuses are engineered to interrupt high fault currents safely and efficiently. A bolted type HRC fuse offers reliable circuit protection in demanding industrial environments.
When selecting a tag fuse, consider the following criteria:
