FRS-R-150 from Bussmann (Eaton) is a Class RK5 dual-element time-delay fuse rated at 150 A with a 600 VAC maximum (300 VDC), designed to tolerate startup surges while protecting power circuits. It delivers an interrupting rating of 200 kA at 600 VAC and 20 kA at 300 VDC, and its body measures about 1.61 inches in diameter and 9.63 inches long. This non-indicating, dual-element fuse provides motor overload protection with time-delay characteristics, suitable for motor circuits, disconnects, and high-current distribution panels in industrial environments.
