ECSR7 - 7Amp Fuse

ECSR7 - 7Amp Fuse

When you’re dealing with sensitive electrical equipment, the last thing you want is unnecessary downtime from a fuse that trips too easily. That’s exactly where the Eaton ECSR7 comes in. This 7 Amp Class RK5 dual-element time-delay fuse is designed to give you dependable protection for low-amperage circuits while still allowing harmless startup surges to pass through. In real-world applications, that means motors, transformers, and control circuits can power up normally without nuisance interruptions — but still stay fully protected when a true overload or short circuit happens.

Built for commercial and industrial environments, the ECSR7 carries a 600V rating and an impressive 200kA interrupting capacity, so it’s ready for serious fault conditions even in compact control systems. Whether you're maintaining an existing system or replacing a fuse in OEM equipment, this is the kind of component you install when reliability actually matters day to day.
