RST 5-BULK

RST 5-BULK application field and working principle

RST 5-BULK type fuses are used in large-scale switching power supply system, widely used in IT, communications, industrial control, instrumentation, LED display, wind power and other high-voltage protection.

RST 5-BULK type fuse has good protection performance, can ensure the safety of people and equipment in the event of accidents, to improve the reliability of power supply system.RST 5-BULK type fuse is a kind of high-voltage fuse which is improved from DC fuse. These fuses are designed to provide over-current protection for modern electrical systems.

Material

RST 5-BULK type fuse is made of an alloy material which has good thermal conductivity, good arc extinguishing performance and excellent temperature control. The material used in the fuse has good electrical properties and is fireproof, which makes the fuse highly reliable and safe.

The material of RST 5-BULK type fuse has characteristics such as low temperature coefficient, high electrical conductivity, good insulation performance and high mechanical strength. In order to increase the mechanical strength, the fuse is provided with a protective shell.

Working principle

RST 5-BULK type fuse is an over-current protection device. It works by detecting when the current passing through it exceeds the pre-determined limit, and then either melting, opening or explosively breaking, thus disconnecting the electrical circuit, thus preventing further damage. When the circuit is disconnected, the current is stopped and the fuse is removed from the circuit.

RST 5-BULK type fuse consists of a current-carrying element and an arcing contact. When the current passing through the fuse increases, the arc between the arcing contacts and the current carrying element will become stronger and hotter, eventually melting the over-current protection element. This process causes the interruption of the current in the circuit and prevents the circuit from being overloaded.

Advantages

RST 5-BULK type fuse has the following advantages:

• It is suitable for large-scale switching power supply system.
