Fuses for semiconductor protection -3NE1 type1), 690 V AC - 3NE10220

Product Description

Siemens SITOR Semiconductor Protection Fuse – 3NE10220

The Siemens 3NE10220 is a SITOR semiconductor protection fuse from the 3NE1 series, specially designed for the protection of sensitive power semiconductor devices such as thyristors, diodes, IGBTs, frequency converters, UPS systems, and soft starters. These ultra-fast acting fuses provide extremely rapid fault interruption, minimizing damage caused by short-circuit currents in semiconductor applications.

This fuse is widely used in industrial drives, power electronics, converter systems, and automation panels, where standard HRC fuses may not provide adequate semiconductor protection.
