ECSR25 - 25Amp Fuse

ECSR25 - 25Amp Fuse

Electrical systems rarely operate under perfectly steady conditions—and that’s exactly where the Eaton Edison ECSR25 Fuse shines. Whether it’s motors kicking on, equipment cycling, or loads shifting throughout the day, this fuse is designed to handle those everyday fluctuations without overreacting. Instead of tripping during normal startup surges, it allows temporary inrush currents to pass through while still stepping in when there’s a real issue that needs attention.

This 25 amp Class RK5 dual-element time-delay fuse is built to strike the right balance between protection and performance. It helps prevent unnecessary downtime caused by nuisance openings, especially during routine equipment startup. At the same time, it remains ready to respond when current levels exceed safe limits, helping protect your system and the equipment connected to it.

What really sets this fuse apart is its dual-element design. It reacts more gradually to short-term overloads but still responds appropriately when a sustained fault occurs. That means fewer interruptions during normal operation and dependable protection when it matters most.
