Fuses

Fuses are used in a variety of applications to protect equipment from over current situations such as short circuits due to wiring faults or overloads. The 5TT 125Fuse is an industry standard fast acting, dual-element, time-delay fuse.

Applications

The 5TT 125 is designed to provide reliable branch circuit protection in both residential and commercial settings. It is most commonly used to protect branch circuits in panel boards, lighting fixtures, motors, pumps, and a variety of other applications. It is also ideal for use in certain motor-generator sets, energy management systems, and fire alarm systems.

The 5TT125 is a UL-listed Class CC fuse and is Underwriter’s Laboratories approved for use to 32 volts. This makes it suitable for use in a variety of applications. In addition, the 5TT 125 has a three-year warranty and is rated at 125-amps of continuous current.

Working Principle

When current passes through a fuse, the current heats up a strip of metal, which melts away when the current reaches a certain threshold level. The metal strip is designed to break the circuit quickly and prevent damage to any electric equipment connected to the circuit.

Technically speaking, the 5TT 125 is a dual-element time-delay fuse. This means that it has two fusible elements: a fast-acting, low-power element and a higher-power time-delay element. If a low-level of current passes through the fuse, it won’t activate either of the elements. If the current level is high, the fast-acting element will activate and provide some protection. But if the current rises to the level of the time-delay element, then it will activate to provide the extra protection.

The 5TT 125 is UL-listed and is designed to disconnect the power in the event of an overload or short circuit. In addition, the time-delay element helps provide protection against nuisance trips, which can be caused by transients or other momentary current surges.

Conclusion

The 5TT 125 Fuse is an industry-standard, dual-element, time-delay fuse used in a variety of applications to protect electric equipment from over current situations due to overloads or wiring faults. It is UL-Listed, rated for a continuous current of 125 amps, and is appropriate for use in residential and commercial settings. The dual-element construction helps ensure that the fuse will activate at the appropriate level to provide protection and prevent nuisance trips.
