ECNR125 - 125 Amp Fuse

ECNR125 - 125 Amp Fuse

Protecting critical electrical equipment starts with choosing the right fuse, especially in systems where motors, compressors, and other heavy-duty loads create temporary startup surges. The Eaton Edison ECNR125 Fuse is designed to handle those demanding conditions while providing dependable overcurrent protection for commercial and industrial electrical systems. With its 125 Amp rating and dual-element Class RK5 design, this fuse helps keep equipment operating smoothly by allowing normal inrush currents to pass without unnecessary interruptions.

Whether you're maintaining a motor control center, supporting facility power distribution, or replacing a fuse in an industrial machine, the ECNR125 delivers the performance needed to help protect valuable equipment from overloads and short circuits. Its 200 kAIC interrupting rating offers a high level of fault-current protection, making it suitable for applications where safety and reliability are important considerations. The compact design also makes installation straightforward in a variety of electrical systems, while Eaton's long-established fuse technology continues to be used across commercial and industrial environments.
