PSR072FL0630Z

Electrical specialty fuses are electrical protection devices that protect current-carrying circuits and wiring systems from damage due to excessive current flow. The fuses interrupt the circuit if a fault current is detected, thus minimizing circuit damage and potential injury.

The PSR072FL0630Z is a 70A, 600V, slow blow time-delay fuse. It is a cylindrical style fuse with silver-plated contacts. The time-delay element classifies the fuse as a "DC Type E," meaning that it works to slow down the trip time of the fuse when used in an AC circuit, which reduces nuisance trips. The fuse is qualified for UL E4286, CSA Class 1422-01, and IEC 60127-4.

Applications

The PSR072FL0630Z is designed for applications in a variety of industries ranging from industrial and commercial to residential buildings. In commercial and industrial applications, it helps protect equipment and wiring from potential damage due to short circuits or other conditions. In residential settings, it helps protect appliances, electronics, and other wiring from overcurrents and potential risk of fire. It is typically used in motor protection and control circuits, as well as for protection of lighting systems.

Working Principle

The PSR072FL0630Z works on the principle that current flowing through the fuse element generates heat. This heat works to slowly melt the fuse element and open the circuit. If there is a short circuit, the high current draw causes the element to quickly melt, opening the circuit and protecting the wiring system. The time-delay element works to slow down the trip time to prevent nuisance trips when used in an AC circuit.

The fuse comes with two silver-plated contacts which make contact with compatible fuseholders. The contacts provide a reliable connection between the fuse and the fuseholders, and help reduce arcing. The fuse also features a high dielectric strength of 2.8 kV between the contacts and fuse body.

The PSR072FL0630Z is designed for use in a variety of applications, and can help protect against potential damage due to short circuits, overcurrents, and other conditions in commercial, industrial, and residential applications.
