Littelfuse FLSR025ID Cartridge Fuse 25A 600VAC 300VDC Time Delay Indicator

The FLSR025ID from Littelfuse is a versatile service entrance switch designed to enhance operational efficiency in various applications, including distribution panelboards and industrial control panels. Its innovative Indicator fuse technology not only reduces the inventory needed for fuses but also allows quick identification of open fuses via a simple glance at the indicating window, eliminating the need for manual testing. With an impressive interrupting rating of 20,000A at 300VDC and a time-delay characteristic, this fuse excels in providing protection for fully-rated panelboards and load centers, minimizing both downtime and the risk of equipment damage. Furthermore, the design improves safety by offering built-in blown fuse indication, ensuring that operators can quickly and safely assess their circuits without unnecessary exposure to live components.
