004373614 electrical specialty fuses are designed to protect overheating motors, overloaded circuits, and short-circuit conditions. Fuses are found in applications ranging from business operations, residential homes, and electric utility companies. It is designed to protect circuits and devices from short-circuits and over-loads.

A fuse is basically a thin wire conductor with a melting point that operates as an overload protection device. When too much current passes through the conductor, the wire overheats and melts, thus interrupting the flow of electricity. The melting point of the fuse is achieved by the selection of proper material and size of the conductor.

Safety standard fuses are designed to protect circuits against a certain amount of current over a designated amount of time. To determine the fuse size required, a current vs. time chart is consulted to identify the desired characteristics needed to protect the circuit. As the current in a circuit rises, the electric energy (wattage) is converted into heat energy. The heat then causes the wire in the fuse to increase its temperature until it reaches its melting point and "blows" the fuse.

Electrical specialty fuses also vary from standard safety fuses, in that they are designed to open quickly when a preset overload or short-circuit condition occurs. This helps protect circuits from excessive current draw or short-circuits resulting in premature damage or failure. When selecting a specialty fuse, the current stack dimensions, voltage rating, mounting configuration, and terminal style are all considered.

When power enters the building, special integral fuses and circuit breakers are installed in the electrical panel to protect against dangerous and excessive current draw from appliances and motors. Voltage fluctuations can also cause circuits and appliances to malfunction and fuses are often used to protect against these occurrences as well. The maximum amperage ratings of all devices connected to any one circuit should always be below the maximum rating of the circuit\'s fuse or circuit breaker.

Integral fuses are permanently connected and become part of the circuit that they are protecting. The fuse is a single unit and is typically found as part of the circuit breaker device. Integral fuses have a wide variety of applications and are available in various sizes and temperatures to suit most any application.

Electrical specialty fuses are a great way to provide protection against short-circuits and overloads, as well as dangerous voltage fluctuations. By understanding the current, time, and voltage requirements of the circuit they are protecting, proper selection of a fuse can be easily made. With a wide variety of fuse sizes and styles available for most any application it\'s easy to stay safe and protected.
