125NH1GL fuses are type GL current limiting fuses, which are designed for the protection of transformers, distribution and other power system applications. They are well suited for a variety of industrial, commercial and residential applications including arc flash protection, overcurrent protection, and surge protection. 125NH1GL fuses provide an extra line of defense against dangerous arc flash incidents by limiting the current in the event of a short-circuit.

The 125NH1GL is a silver fusible element with a time-delay element which provides extra protection to larger loads, and is rated for 125A and 600 volts AC. With its large clearance distance, it can also be used in applications where other current limiting fuses of rated ampacity may be too short.

The 125NH1GL fuse is encased in a polyvinyl chloride (PVC) body with an external copper cap. The external copper cap provides an electrical connection for the fusible element. When the fusible element melts, it trips the external fusible link, disconnecting the power from the load.

The working principle of the 125NH1GL fuse is simple. When the current in a circuit exceeds the rated value of the fuse by a predetermined amount, the external fusible element melts and trips the external fusible link. This interrupts the circuit, breaking the electrical connection from the power source to the load, and protects the circuit and connected equipment from potential damage.

125NH1GL fuses are typically used to protect sensitive and valuable equipment from overcurrent, as well as to limit the probability of an arc flash occurrence. The use of this type of fuse can provide an added level of safety and protection for both personnel and equipment, while being effective in controlling and mitigating the effects of an arc flash incident.

125NH1GL fuses are well suited for use in a variety of areas, including industrial, commercial, and residential settings. They can be used to protect motors, transformers, distribution boxes, and other electrical equipment, as well as residential projects. In each instance, the 125NH1GL fuse provides an extra layer of protection for personnel and equipment from overcurrent events and arc flash.
