Combination alarms signal the tripping of a fuse by a clear color change from red to white. 2. Greater safety when replacing thanks to insulated grip lugs. 3. High selectivity at low cost. 4. Long-term and safe operation thanks to silver-plated contact blades. 5. Fuse links are available rated from 2 A to 1250 A and in sizes 000, 00, 0, 1, 2, 3, 4 and 4a.
