ECSR450 - 450Amp Fuse

ECSR450 - 450Amp Fuse

The Eaton ECSR450 is a 450 Amp Class RK5 dual-element time-delay fuse designed to provide dependable overcurrent protection for high-capacity commercial and industrial electrical systems. Built to safeguard motors, transformers, feeders, and other critical power distribution equipment, this fuse is engineered to withstand temporary inrush currents during equipment startup while responding quickly to sustained overloads and short-circuit faults. Its dual-element construction helps minimize nuisance fuse operations, allowing equipment to continue running through normal startup conditions while maintaining a high level of circuit protection. Whether you're maintaining existing electrical infrastructure or replacing a fuse in demanding applications, the ECSR450 delivers the performance and reliability professionals rely on to keep operations running safely and efficiently.

Rated for 600 VAC and featuring a 200 kA interrupting capacity (kAIC), the Eaton ECSR450 is well suited for installations where high fault-current protection is essential.
