ECSR500 - 500Amp Fuse

ECSR500 - 500Amp Fuse

When your electrical system demands dependable overcurrent protection for high-amperage applications, the Eaton ECSR500 delivers the performance professionals rely on. This 500 Amp Class RK5 dual-element time-delay fuse is engineered to help protect motors, transformers, feeders, branch circuits, and other critical electrical equipment from damaging overloads and short circuits. Its dual-element, time-delay design allows temporary inrush currents—such as those experienced during motor startup—to pass without unnecessary fuse operation, helping minimize nuisance outages while maintaining reliable circuit protection. Rated for 600 VAC with a 200 kA interrupting capacity (kAIC), the ECSR500 is well suited for demanding commercial and industrial environments where safety, equipment protection, and system uptime are essential.
