Product Description

Siemens 3NE4120 Semiconductor Protection Fuse – 3NE4 Type, 1000 V, 80 A

The Siemens 3NE4120 is a semiconductor protection fuse from the 3NE4 type range, designed to provide dependable protection for sensitive semiconductor components used in industrial power-electronic and electrical applications. With a rated voltage of 1000 V and rated current of 80 A, it is suitable for high-voltage applications where reliable and fast fault protection is required.

Semiconductor devices such as thyristors, diodes, rectifiers, power converters, soft starters and industrial drive equipment can be vulnerable to excessive current and short-circuit conditions. A dedicated semiconductor protection fuse helps interrupt fault currents rapidly and supports the protection of connected power-electronic components.

The Siemens 3NE4120 can be considered for industrial power conversion equipment, rectifier systems, motor-control applications, automation machinery, OEM equipment and electrical panels. It is suitable for applications where dedicated semiconductor protection forms an important part of the overall electrical protection arrangement.

For correct application, the fuse should be selected according to the complete system requirements, including operating voltage, current, prospective short-circuit current, semiconductor characteristics, installation conditions and required coordination with the protected equipment.
