6420-2T

The 6420-2T is a member of the electrical and specialty fuses family, produced by the trusted company ABC Labs. This particular type of fuse is designed for use in high-level voltage circuits, typically 220Volts AC, and up to 600 Volts DC. It is a times-delay fuse, with a short-circuit breaking capacity of up to 250 amperes. Due to its unique design, the 6420-2T is suitable for most high-level applications, including industrial and domestic uses. Additionally, this product is UL and CSA approved, so you can rely on it to be able to provide the level of safety that these approvals require.

The 6420-2T has a simple working principle. When the current passing through a circuit this fuse is protecting exceeds the rated level, the ceramic body of the fuse expands due to the increase in temperature. This expansion causes the internal silver alloy strip to buckle, opening the internal fuse element. At this point, the fuse has opened and current to the circuit is prevented from passing. The time-delay feature of the 6420-2T ensures that the fuse protects against rapidly occurring changes in current, as it allows for a small spike in current to pass without tripping the circuit.

The 6420-2T is most commonly used in industrial, domestic and commercial applications, especially in those that involve the movement of goods or fluids, such as pumps, swimming pools and solar water heating systems, as well as heavy automotive usage. Typically, these circuits require a greater level of protection and the 6420-2T is the perfect choice, as it offers improved protection in those areas. Additionally, due to the unique design of the fuse element, the 6420-2T also offers a cost-effective solution for high-level protection.

It is important to note that the 6420-2T should be replaced if it trips, in order to ensure that it continues to provide the necessary level of protection. The 6420-2T should only be replaced with the same type of fuse, as other fuses may not be designed to withstand the same level of voltage. Additionally, users should always ensure that the circuit is properly earthed and that the correct fuse rating for the application is used.

Overall, the 6420-2T is a great choice for those looking for reliable, cost-effective protection from dangerous voltage spikes. Its unique design ensures that it will provide the protection required, and its UL and CSA approval means that you can rest assured that it has been extensively tested for reliability and safety.
