Frequently asked questions

Why is the Siemens 3NE1334-2 preferred for semiconductor protection over a gS fuse?

The Siemens 3NE1334-2 has a gR (general purpose rapid) fuse characteristic, meaning it interrupts faults much faster than a gS fuse. This rapid response is critical for protecting sensitive semiconductor devices from damaging overcurrents and voltage spikes during short circuits, minimizing potential equipment damage.
