04761.25MR Application Field and Working Principle

04761.25MR fuses are commonly used in commercial, industrial, and residential applications. They are designed to provide protection from overloads or short circuits in electrical circuits operating at 250 volts or less. This type of fuse is effectively a one-time only thermal device, and its purpose is to open the circuit if the current reaches and exceeds the fuse’s established rating.

The 04761.25MR fuse is hermetically sealed and has a ceramic body with a Nickel-plated brass end cap. It has an Interrupting Capacity rating of 1000 amps at 250 volts maximum, and an Operating Temperature range of -55°C to +125°C. This fuse fits into standard glass-bodied Class RK 5 fuse blocks. It is UL listed, CSA certified, TUV approved, and RoHS Compliant.

Each 04761.25MR fuse contains a fusible metal element that is specifically designed to melt when heated, and is connected between two wires. This element is usually a thin strip of metal that is designed to generate heat as a result of an increase in current flowing through the circuit. The heat generated by this element causes it to expand, which causes the two contacts on either side of the element to separate. When the current stops, the contacts reconnect, restoring the circuit.

The current rating of a 04761.25MR fuse is determined by the gauge of the fusible metal strip, as well as the size of the fuse and the materials used in its construction. When the current flowing in the circuit reaches the rated value of the fuse, the element will heat up and expand. This expansion will cause the two contacts to separate and open the circuit, thus preventing damage to the wiring.

There are several advantages to 04761.25MR fuses. First, they provide protection for circuits against overcurrents or short circuits that can be caused by faulty electrical equipment or wiring. Second, they allow increased levels of current to be used in a circuit, without fear of overloading it. Third, they provide a fast response to overloads, and can be reset after tripping. Finally, they offer an easy and cost-effective way of providing circuit protection.

In conclusion, 04761.25MR fuses are useful in many applications, and are commonly used in residential and commercial buildings. They are designed to protect circuits against dangerous overloads or short circuits, and provide a fast and cost-effective means of circuit protection. The fuse is hermetically sealed and has a ceramic body with a Nickel-plated brass end cap. Finally, the fuse has an Interrupting Capacity rating of 1000 amps at 250 volts maximum, and an Operating Temperature range of -55°C to +125°C.
