125NH2M

Electrical Specialty Fuses are used to protect electrical circuits from potential overloads. The 125NH2M fuse provides superior protection against overloads and short circuits due to its metal casing, robust construction and superior operating characteristics.

The 125NH2M has a current rating of 125 amps at 250 volts AC with a current interrupting rating of 500 amps. It is designed for use in both commercial and industrial applications, such as HVAC equipment, dryers, ovens, heavy-duty motor controllers, and other electrical circuits. The fuse is UL listed and meets the requirements of UL 248 for interactive and supplementary protection.

The 125NH2M is constructed of an inner metal tube surrounded by ceramic or alkaline earth glass beads. This tube is surrounded by a metal casing with a threaded base for secure installation. The casing protects the fuse from mechanical shock and vibration and provides superior temperature stability. The fuse has a rated current of 125 amps and a rated voltage of 250 volts AC. The 125NH2M has an interrupting rating of 500 amps at 250 volts AC.

The 125NH2M fuse has a unique working principle. It is designed to “nullify” incoming current before it reaches the protected circuit. This is done by passing the current through the ceramic or alkaline earth glass beads, which have an extremely high permeability to large currents. The beads act like a filter, allowing only the necessary small current to pass through, while blocking or “nullifying” the higher current. This helps to maintain the integrity of the protected circuit, as well as the fuse itself.

The 125NH2M fuse also offers superior protection against short circuits. A short circuit is caused when two or more electrical wires come into contact and create an excessive amount of current. The high current can damage the circuit, melt the insulation and even start a fire. The 125NH2M is designed to protect the circuit by automatically tripping when the current exceeds its rating. This helps prevent serious damage, fires and possible injury.

The 125NH2M is a robust and reliable electrical fuse that is suitable for use in a wide variety of applications. Its metal casing and compact size provide superior protection against overloads and short circuits. In addition, its unique working principle ensures that the circuit is adequately protected from both overloads and short circuits. The 125NH2M is UL listed and meets the requirements of UL 248 for interactive and supplementary protection.
