Fuses are common electrical components used in various types of applications to protect electrical devices from overloads and other electrical hazards. The 0218.100MXBP is a type of fuse known as a Time-Delay Fuse for its specialty of delaying the response time when it encounters an overload current. This article will discuss its application field and working principle.

Application Field of 0218.100MXBP

The 0218.100MXBP is designed to protect against overcurrent conditions causing possible damage to electrical circuit, equipment, and components. It features a time-delay characteristic that allows it to delay responding to overcurrents of short duration while still having the capacity to quickly respond to prolonged or elevated overloads. The 0218.100MXBP is primarily used in industrial, motor control, and lighting applications. It is also suitable for powering electrical panels, transformers, and rectifiers in commercial, residential, and institutional buildings.

The 0218.100MXBP is UL and CSA rated for 10,000A maximum interrupting rating and 1,200A current-limiting rating. It can be used in both single and three-phase circuits, and it can also be reverse mounted so that the terminals are accessible from the front of the fuse. This feature makes the fuse suitable for applications in which the front side of the fuse is not accessible, such as in enclosed motor control centers.

Working Principle of 0218.100MXBP

The 0218.100MXBP Time-Delay Fuse is designed to sense overcurrent conditions and keep the circuit protected for a certain period of time before tripping. It features a current rating of 10A, a sustained interrupt rating of 10kA, and a melt-setting time of 12 seconds. It also incorporates an operating voltage of 600VAC.

When the fuse senses an overload current, the fuse element begins to melt. This increases the resistance of the element, which slows down the current flow through the fuse. Rather than immediately tripping like a regular current-limiting fuse, the 0218.100MXBP will delay its response and allow the current to flow for a period of time before it trips. This prevents small momentary overloads from causing circuit interruption.

The 0218.100MXBP also has a thermal-magnetic trip, which ensures that prolonged or elevated overloads will be quickly responded to and the circuit will be interrupted. This feature also ensures that the fuse will never melt beyond its melt-setting time and that the correct replacement fuse can be quickly identified and installed.

Conclusion

The 0218.100MXBP Time-Delay Fuse is designed for industrial, motor control, and lighting applications and is UL and CSA rated for 10,000A maximum interrupting rating and 1,200A current-limiting rating. It is designed to sense overcurrent and delay its response time, while still responding quickly to prolonged or elevated overloads. It features a current rating of 10A, a sustained interrupt rating of 10kA, and a melt-setting time of 12 seconds.
