0287025.U

Fuses

Fuses are used to prevent electrical damage from overloads and short circuits. The most common type of fuse is the 0287025.U. This type of fuse has a built-in safety feature that allows it to be used in electrical circuits, such as those used in industrial settings. This type of fuse is also known as a fuse breaker.

The 0287025.U is a variation on the traditional class CC fuse. It is designed to be used in electrical applications where slow overloads or short circuits need to be protected from. It has a physical size of 1/2" x 1/4", allowing it to fit into small spaces.

Application Field

The 0287025.U is classified under the UL Standard 4248, and is designed to protect AC and DC circuits from overloads and short circuits. It can be used in both residential and commercial applications. It is suitable for circuits with maximum current ratings of 20 to 60 amps, and rated currents up to 60 amps. The fuse is UL Listed, and is suitable for use in ungrounded circuits of 120/240 volts.

Working Principle

The 0287025.U fuse has a metal strip that heats up when it is overloaded. When the temperature reaches a predetermined level, the strip melts and opens the circuit, disconnecting the current from reaching the device. This type of fuse will reset itself when the temperature of the circuit drops back to a safe level.

The fuse also has a built-in design element that blocks out the presence of any DC offsets. This helps prevent false readings in the circuit, ensuring that the fuse is working correctly.

Conclusion

The 0287025.U is designed to protect AC and DC circuits from overloads and short circuits. It has a metal strip that melts when the temperature reaches a predetermined level, disconnecting the current from reaching the device. The fuse also has a built-in design element that blocks out the presence of any DC offsets, ensuring that it is working correctly.
