Cooper Bussmann 100A German Standard Fuse, NH000, 690V ac, 78mm

Need to protect sensitive semiconductor components, such as diodes, thyristors and SCRs, from damage resulting from short circuits? Choose this German Standard fuse from Eaton. It's a fast-acting aR-type fuse that blows in milliseconds in the event of a fault. The offset slotted tags are compatible with many standard electrical distribution panels and let you make a secure connection, even in vibrating equipment. Compact dimensions of 100 (L) x 40 (H) x 21mm (W) minimise heat loss to keep your system running cool.

• Status indicator lets you check easily whether the fuse has blown
• Square body allows for easy handling and quick identification

This aR-type fuse provides protection from short circuits only. It doesn't offer any protection from overcurrent, so it shouldn't be used as a replacement for a gR-type fuse.

A thyristor is a four-layer semiconductor device that's used as a high-speed switch. Thyristors can replace mechanical relays as they have no moving parts and are therefore more reliable.
