5ET 630-R

The 5ET 630-R is a type of fuse, a device designed to prevent an electrical circuit from carrying out too much current. The 5ET630-R is self-resetting and can be used to protect circuits from high current levels ranging from 1.12A to 1.56A. This type of fuse is generally used in power supplies, machine tools, communication equipment, IT products, consumer electronics, and many other applications.

The 5ET630-R fuse consists of two components: the contact and the thermal element. The contact is a bent metal strip that runs across the top of the fuse, forming a connection between the two contacts on either side of the case. The thermal element is located between the contacts and is made of a material that heat up quickly and breaks the connection when excessive currents are detected. The fuse only needs to be replaced after it has tripped due to an overload.

The working principle of the 5ET630-R is that when the current in the circuit is too high, the thermal element begins to heat up and eventually reaches its breaking temperature, which causes the metal contact to break and disconnect the electric circuit. This protects the equipment in the circuit from further damage due to the excessive current. After the connection is broken, the circuit cannot be restarted unless the fuse is replaced, as the thermal element has been damaged and is no longer able to sense current accurately.

The 5ET630-R is a reliable, low-cost fuse option that can be used in a variety of applications. It is designed to withstand high temperatures and offers a wide current range, making it a good choice for a variety of protection. Depending on the application, it can be used in both AC and DC circuits, as well as in both single-phase and three-phase systems.

In summary, the 5ET630-R is a type of fuse designed to protect circuits from high current levels. It consists of two components—the contact and the thermal element—and works by heating up the thermal element to break the connection when excessive currents are detected. The 5ET630-R is an ideal fuse solution for a variety of applications, including power supplies, machine tools, communication equipment, IT products, consumer electronics, and more.
