170M6269 Application Field and Working Principle

Electrical, Specialty Fuses are used for various electrical isolation, protection, and specialized applications including active electronic components. The 170M6269 is a particularly effective electrical component designed specifically for applications such as solar fuses.

Features of the 170M6269

The 170M6269 is a DC rated low voltage fuse with chemical film construction. It is UL recognized, RoHS compliant, CSA and is available in four voltages (25V, 32V, 48V, and 300V). The fuse features a 250A interrupt rating, up to 600A peak current, and a minimum melting current of 140A. Its operating temperature range is between -25C to 85C, with a tolerance of 10%. It is available in lengths of 22 mm, 26 mm, 29 mm, 33 mm, and 39 mm.

Application Field

The 170M6269 is best suited for a variety of DC applications where voltage is stable and current flow is lower, such as photovoltaic (PV) fuses. This device is used to protect PV cells and modules from overcurrent during installation and operation. It is also commonly used in car electronics, heating and ventilation systems and other high-performance electronic applications.

Working Principle

The 170M6269 is a low voltage fuse utilizing a chemical film construction. It has a fast-acting current-limiting design and responds to overcurrent conditions by providing instantaneous inter-rup-tion. This fuse consists of a solid conductor that has a layer of an inert chemical material called mu-metal. This mu-metal is electrically conductive and generates a magnetic field in response to current passing through the conductor. The material has a melting point that is lower than the rated current of the fuse, which causes it to become brittle and break when the current is exceeded. This action opens the circuit and protects the other components.

Conclusion

The 170M6269 is a versatile and robust low voltage fuse designed specifically for applications such as solar fuses. It features a UL recognized construction, an impressive interrupt and peak current rating, an operating temperature range of -25C to 85C, and lengths of 22 mm, 26 mm, 29 mm, 33 mm, and 39 mm. This device is ideal for DC applications where voltage is stable and current flow is lower, such as photovoltaic (PV) fuses.
