Ultra-rapid fuse

Class aRClass gSClass gR

Other applications: At home in many operating classes Our UR fuses cover the whole range of uses for power semiconductors, starting from classical short-circuit fuses mounted directly on the semiconductor with the back-up operating class, aR, and extending to the full-range operating class gR, which is also able to protect against overload currents, and also to operating class gS, originally introduced by SIBA as operating class gRL. This product protects not only the semiconductor itself, but also the leads. And in doing so, it preserves your investment from harm.
