Industrial ECSR-125 Time-Delay Dual Element Fuse

The Edison ECSR125 is a 125 A, 600 V dual-element time-delay fuse (Fusetron) in the Edison ECSR family, a UL-listed Class RK5 device designed for branch and feeder protection in motor drives, panel boards, load centers, and other power-distribution applications. Its dual-element, time-delay design allows temporary overloads and motor inrush while still providing fast short-circuit protection, with a 600 VAC rating, a minimum 10-second delay at 500% rated current, and an interrupting rating of 200 kA RMS symmetrical. The fuse body measures 1.61 inches in diameter and 9.63 inches long and uses blade-terminal connections for secure mounting in compatible fuse blocks. UL, CSA, and CE certifications accompany the device, making it suitable for non-inductive loads, general-purpose lighting and heating, AC drives, and other industrial applications in commercial settings.
