004235109

Electrical, Specialty Fuses

004235109 is a type of electrical specialty fuse commonly used in fusing and circuit protection applications. It is a range of current and voltage rated products created to protect fusing systems from catastrophic failure caused by an overload or by a short circuit. The fuse is designed in such a way that it limits the flow of current and opens the circuit when a fault is detected.

Application Field

The 004235109 current and voltage rated products are used for circuit protection in a wide range of industrial, commercial, and domestic applications, such as, office machines, computers, TVs, home appliances, automotive, telecommunication, lighting, power tools, and short-circuit testing equipment. It can also be used for direct current (DC) power regulation.

The fuse is also used for overvoltage protection, overcurrent protection, and inrush current limitation for higher current DC electronic systems. Additionally, the 004235109 fuses are used in various safety circuits in elevators, escalators, fire alarms, and other safety systems.

Working Principle

The 004235109 fuse is a dual element fuse with a current sensing disc and a voltage sensing disc. When the current travels through the fuse, it generates a magnetic field around the input line. If the current exceeds the electric current rating, the magnetic field becomes stronger. This leads to an increase in the electrical resistance in the current sensing disc, which causes the fuse to open the circuit. The voltage sensing disc also detects over-voltages and the fuse opens the circuit if the voltage exceeds its voltage rating.

The fuse operates on a time-current characteristic curve which is plotted by the current-time coordination of several overcurrent and short-circuit protection tests. The curve specifies the time it takes for the fuse to open the circuit, with the current increasing from minimum to maximum current. The 004235109 fuse has a time-current characteristic curve that is resistant to current leakage and has a fast blow response time, making it suitable for niche applications.
