TPS-25V

TPS-25V is a specialty fuse designed and manufactured by Grayhill that offers overcurrent protection in electrical applications. It features a wide range of current ratings from 0.10A up to 60A, and provides high interrupting ratings for a wide variety of applications. The fuse has a low cost, is easy to operate, and is also UL recognized.

The TPS-25V is designed for the protection of motors, transformers, capacitors, generators, and other electrical components in industrial, commercial, and residential environments. It works by sensing an overcurrent condition and disconnecting the current at a predetermined level. During an overcurrent scenario, the fuse will blow, thereby protecting the circuit from over-voltage or short-circuiting. When the overcurrent condition is cleared, the current resumes as before.

The working principle of the TPS-25V is based on a thermal-magnetic trip. The fuse consists of an overcurrent sensing element consisting of a metal strip that is heated up upon the application of an overcurrent. When the metal strip reaches a certain temperature, it triggers an internal magnetic latching mechanism which opens the circuit.

The TPS-25V comes in two types: normal acting and time delay. The normal acting fuse will blow instantly when the overcurrent is sensed, whereas the time-delay fuse has a time-delay feature that prevents the fuse from blowing until the current has remained at an over-current level long enough for the internal metal strip to reach its reference temperature. This allows the fuse to be used in a wide variety of applications, where a time-delay feature is desired.

The TPS-25V provides protection from motor overload, short circuits, and lightning strikes. It accepts high voltages up to 600V and current ratings up to 60A. It is easy to handle and maintain, and provides a fast, reliable, and cost-effective protection solution for a wide variety of electrical applications.

The TPS-25V fuse is a UL recognized component, and it is compliant with IEC60269 and EN 60269 standards. It is widely used in industrial, commercial, and residential applications, and offers excellent performance and reliability in the field.
