    Tag Fuses

    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.

    How Tag Fuses works

    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.

    What are the Different Types Of Tag Fuse?

    Tag fuses are available in several configurations, each suited to specific installation and performance requirements. The main types include:

    Bolted Tag Fuses

    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

    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

    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.

    Slotted Tag Fuses

    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.

    High Rupturing Capacity (HRC) Fuses

    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.

    Industrial Applications of Tag Fuses

    • Power distribution: Tag fuses are used in distribution panels and switchboards to safeguard transformers, feeders, and sub-circuits against overloads and short circuits.
    • Motor protection: In motor-driven systems, tag fuses help prevent damage caused by excessive current during startup surges or mechanical malfunctions.
    • Cable protection: Tag fuses mitigate the risks of cable overheating and fire hazards by interrupting current flow during overload conditions.
    • Manufacturing and processing plants: In environments with complex machinery and automated systems, tag fuses ensure faults are quickly isolated to avoid system-wide disruptions.

    How to Choose the Right Tag Fuse

    When selecting a tag fuse, consider the following criteria:

    • Rated current and voltage: Confirm compatibility with your circuit's electrical parameters
    • Breaking capacity: Select HRC fuses for circuits exposed to high potential fault currents
    • Fuse speed: Determine whether a fast-blow or time-delay fuse is more appropriate
    • Tag orientation: Choose among bolted, centred, offset, or slotted tags to suit your holder configuration
    • Application category: Refer to designations such as gG, aM, or gM to match functional requirements
    • Environmental conditions: Ensure the fuse is suitable for operating in your application’s temperature, humidity, or exposure levels

    Tag Fuse Installation

    Proper installation ensures optimal performance and safety:

    1. Disconnect power: Always isolate the power source before beginning installation.
    2. Verify compatibility: Confirm that the fuse’s ratings and tag type match system specifications.
    3. Position the fuse: Align the tags within the holder and bolt or snap the fuse into place securely.
    4. Reinstate power: Restore the power supply and confirm normal circuit function.
