Product Description
The Federal Pacific/ Reliance ECSR25 is a 25 Amp, 600 Volt AC, Class RK5 dual‑element time‑delay fuse engineered for dependable overcurrent protection in a wide range of electrical systems. With its time‑delay and current‑limiting design, the ECSR25 tolerates harmless inrush currents — such as those from motors or transformers — yet reacts quickly under sustained overloads or short‑circuit conditions. It is ideal for feeders, branch circuits, panelboards, motor circuits, transformers, lighting/heating, and general‑purpose industrial loads, offering robust protection while reducing nuisance trips.
