F0402E0R50FSTR Circuit Protection

F0402E0R50FSTR Application Field and Working Principle

Introduction

F0402E0R50FSTR is a kind of fuse generally used in electronic equipment and circuits. It is a component used to protect against unexpected short circuit or overload conditions, which can cause serious damage to the system. With a low rated current of 50A, it is suitable for most high-power applications.

Types of F0402E0R50FSTR

F0402E0R50FSTR is a type of fast-blow fuse with a rated current of 50A and a rated voltage of 150VAC. The fuse is composed of a thermoplastic shell, a pure metal contact, a high melting glass tube, a spring and an insulating substrate. The metal contacts can carry current when not overloaded, effectively preventing the circuit from being damaged by short-circuit, overload or overvoltage.

Application Field

F0402E0R50FSTR is mainly used in large-power electrical and charging equipment. It is widely used in electric vehicles, power meters, UPS, chargers, medical equipment, power converters, lighting and other equipment, providing safe and reliable protection for the equipment and its components.

Working Principle

When the system is under normal working state, the F0402E0R50FSTR carries a small current, and the temperature around the fuse is relatively low. When the system has an unexpected high-current short-circuit or overload, the temperature around the fuse increases rapidly, and the heat melts the inner high melting glass tube relatively quickly. The melting of the metal contact breaks the current-carrying circuit, thereby limiting current to protect the circuit.

Conclusion

F0402E0R50FSTR fuse is a kind of fast-blow fuse with low rated current and wide application field. It is mainly used in large-power electrical and charging equipment, such as electric vehicles, UPS, medical equipment and power converters. When there is an unexpected short-circuit or overload, the contact in the fuse will be melted and the current-carrying circuit will be cut off, thereby providing circuit protection to the device.
