Fuses:0239003.HXE application field and working principle

Introduction

Fuses are electrical devices that protect circuits and equipment from over-current conditions due to overload, short circuit, and ground fault. Fuses are the most economical form of overload protection, widely used in many electrical and electronic circuits. It provides short circuit protection and rated current protection for electrical equipment, preventing overload and short circuit, ensuring the safe operation of electrical equipment, and ensuring good electrical performance and reliability of the circuiting. The 0239003.HXE is a type of fuse used for a range of applications.

Application Field of 0239003.HXE

The 0239003.HXE is a time-delay fuse for use in aircraft-type high-power applications. It is designed for high durability in harsh electrical conditions. It is suitable for panel, switchboard, power distribution, and contorl circuits. The FKR-16 series fuses are rated for 16.00 amperes at 600 volts AC/DC, with time delays of 0.025, 0.35, 0.45, 1.00, and 1.5 seconds.The fuse has high breaking capacity and can withstand up to 5000 amperes of surge current for power line applications for up to 200kW AC systems. It is used in automation, green energy, transportation, and power control systems. Due to its high durability, the 0239003.HXE is suitable for a variety of conditions, from harsh to less hostile environments.

Working Principle of 0239003.HXE

The working principle of the 0239003.HXE is based on a heat-sensitive element such as a resistor, a fuse wire, a resistor, or a bimetallic strip. When the current passing through the fuse exceeds the rated current, the fuse element will heat up. When the temperature of the element reaches a certain value, the fuse will open, thus protecting the circuit from over-current or short circuit.The 0239003.HXE is an arc fault current interrupter. It includes two separate electromechanical switches, one for AC and one for DC. The two switches are connected in series to the two main supply lines of the circuit. The AC switch has a pressure-sensitive element and an arc-chamber. The DC switch has an arc-dashboard and a sensor. When the current passing through the 0239003.HXE exceeds its rated current, the AC switch is activated first. It sends an arc of electricity into the arc-chamber. This arc of electricity causes the pressure-sensitive element to open, cutting off the main supply line. This in turn trips the DC switch, which sends an arc-dashboard between the supply line and the sensor. The arc-dashboard acts as an additional current limiter, reducing the current to a safe level.

Conclusion

The 0239003.HXE is an efficient and reliable fuse used for a range of electrical applications. Its high breaking capacity makes it suitable for circuits and equipment that require a high level of protection from shocks and overloads. It is designed for use in aircraft-type high-power applications and is used in a variety of industries including transportation, electricity, and automation. The 0239003.HXE works on the principle of heat-sensitive elements such as a fuse wire or bimetallic strip. When the current passing through the element exceeds the rated current, the fuse element heats up and opens, thus cutting off the main power supply and protecting the circuit from overload or short circuit.
