Bussmann is a leading brand of circuit protection products manufactured by Eaton. Formerly known as Cooper Bussmann, the brand is now fully integrated into Eaton's electrical division.
If you have a transparent glass fuse, you can visually inspect it. If the internal wire is broken or blackened, the fuse has blown. For non-transparent fuses, you can use a multimeter set to continuity to check if the fuse is still intact.
Fast-acting fuses blow almost immediately when their rated current is exceeded, providing protection for sensitive electronics. Time-delay (or slow-blow) fuses are designed to tolerate brief surge currents, such as those caused by starting motors, without blowing.
