2E8PT5.5


A 2E8PT5.5 is an electrical fuse that is used to protect electrical circuits from overheating and overloads. The 2E8PT5.5 is designed to provide reliable over-current protection for industrial and commercial applications. This fuse type is UL Listed and meets UL 94-0, Type SE and Type GPR requirements for use as supplementary protection of circuit breakers.

Applications

The 2E8PT5.5 fuse is used to protect circuit branches, especially those that are rated for high currents. It is also used to protect medium voltage equipment such as transformers, pumps, and electric motors. In addition, it is used to protect devices such as relays, switches, contactors, solenoids, sockets, cable connection terminals, and high current circuits.

Working Principle

A 2E8PT5.5 fuse uses a high-temperature fuse element as its primary protection device. This fuse element is made up of an electrically conductive material, such as a metal or an alloy. When the current through the fuse element exceeds the fuse rating, the heat generated by the resistance of the material causes it to melt. This releases the energy of the arc, which breaks the circuit.

The 2E8PT5.5 has a time-delay element that can help protect against short-term overloads. This time-delay element is made up of a combination of ceramic and metallic components. It provides a second level of protection by providing a delay before the fuse trips. This delay allows the device to respond to faults and overloads before they cause any damage.
