A motor, for example, can draw considerably more than its running current for a short time during startup. Transformers can produce similar inrush conditions when energized. A properly selected time-delay fuse is designed to account for these normal events rather than treating every brief surge as a sustained overload.\u003cbr\u003e\u003cbr\u003eThat makes the FLSR050-ID a practical fit for appropriately specified motor branch circuits, motor control equipment, transformers, industrial machinery, feeders, switchboards, service equipment, and general industrial power-distribution circuits requiring Class RK5 protection. The indicating feature is particularly handy in facilities with multiple fused circuits, where quickly locating an open fuse can simplify troubleshooting and maintenance.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
