PSR030FS0400Z

PSR030FS0400Z Application Field And Working Principle

PSR030FS0400Z speciality fuses are designed to protect electrical and electronic circuits. These fuses are used in consumer appliances, industrial machines, and vehicles. They are made in a variety of shapes and sizes for a wide range of application fields such as motor starting, surge protection, media protection, voltage pretection, overload protection, and overcurrent fault protection.

The PSR030FS0400Z is a low-voltage specialty fuse, with an interrupting capacity of 400 Amps (maximum continuous current of 500 amperes). It features a fail-safe one-piece design that eliminates potential pinch points. The fuse is also highly sensitive, with an extremely fast-acting response time.

Working Principle

The PSR030FS0400Z fuse’s working principle is based on a simple concept: when the current passing through the fuse reaches a pre-determined level, the fuse will break the current flow and protect the circuit. This process is known as fusing or “blow”.

When the current passes through the fuse, an arc is established between a contact at one end and the fuse element at the other end. The arc is then drawn further along the fuse element, causing it to melt and disconnect the circuit. The fuse element must be replaced in order to reset the circuit.

Typical Applications

The PSR030FS0400Z specialty fuse is designed for a wide range of applications such as motor-starting, surge protection, media protection, voltage protection, overload protection, and overcurrent fault protection. One of the most common applications is to protect a circuit from overloading or short-circuiting. These fuses can be used in consumer appliances, industrial machines, and vehicles.

Conclusion

In conclusion, the PSR030FS0400Z speciality fuse is a low-voltage fuse designed to protect electrical and electronic circuits from overloading and short-circuiting. Its fail-safe one-piece design eliminates potential pinch points and its high sensitivity makes it extremely fast-acting. These fuses are commonly used in consumer appliances, industrial machines, and vehicles.
