Fusetron FRS-R-400 Dual Element Time Delay Current Limiting Fuse

Fusetron FRS-R-400 dual-element time-delay current-limiting fuse is a protective device designed to guard electrical circuits by interrupting overcurrent conditions. Its dual-element construction and time-delay design tolerate temporary overloads and inrush currents without nuisance trips, while still limiting fault current to protect wiring and components downstream. As a current-limiting fuse, it minimizes energy that can reach damaged parts during a fault, helping to reduce potential damage and maintain system safety. The FRS-R-400 designation identifies this specific model within the Fusetron family, providing a defined form factor and rating for use in electrical protection schemes.
