Littelfuse FLSR030 Class RK5 Fuse 30A Slo-Blo 600VAC 20000A Interrupting Rating Industrial Cartridge

The FLSR Series from Littelfuse provides an essential solution for service entrance switches and motor control centers, capable of handling mains and motor branch circuits with absolute reliability. Designed for precision, these devices utilize automated manufacturing to ensure consistent performance in response to overloads and short circuits, making them vital for protecting fully-rated panelboards and loadcenters. With a remarkable interrupting rating of 200,000 A.I.R., they effectively manage overcurrents and deliver faster acting short circuit protection compared to traditional non-current limiting mechanical devices. Ideal for a variety of applications, including industrial control panels and distribution panelboards, this circuit protection device is built to accommodate general purpose circuits, providing peace of mind for a range of electrical installations.
