Frequently asked questions

What is the difference between gR and aR fuse classes for Siemens SITOR fuse links?

The 'gR' (general purpose, rapid) class, like in the Siemens 3NE4222, is for general circuit protection and offers fast-acting response. The 'aR' (amperes rapid) class, found in other Siemens fuse links, is specifically designed for extremely fast protection of power semiconductors and reacts even quicker to fault currents.
