ECSR9 - 9Amp Fuse Description

ECSR9 - 9Amp Fuse

The Eaton ECSR9 is a 9 Amp Class RK5 dual-element time-delay fuse engineered to provide dependable overcurrent protection in commercial and industrial electrical systems. Designed to withstand the temporary inrush currents that occur during motor startup and transformer energization, this fuse helps reduce unnecessary openings while continuing to deliver fast, reliable protection when true overloads or short circuits occur. Whether you're protecting motor circuits, branch circuits, or other power distribution equipment, the ECSR9 delivers consistent performance that helps improve system reliability and minimize downtime.

Rated for 600 volts AC with a 200 kA interrupting capacity (kAIC), the Eaton ECSR9 is built to safely interrupt high fault currents in demanding electrical environments.
