3NE semiconductor protection fuses are Siemens' protectors for variable-frequency drives and soft starters. They offer very fast switching speeds and reliable short-circuit protection. 3NE semiconductor protection fuses have a unique design that integrates semiconductor protection and line protection, which greatly reduces costs, space and installation costs. 3NE semiconductor protection fuses have a rated current of 1-1200A and have high frequency cyclic load capability, which can ensure long-term operation.
The Siemens 3NE series fast fuses are designed for semiconductor protection in inverters and soft starters, offering rapid interruption of short‑circuit currents and high cycle‑load capability. The 3NA series provides similar protection for general circuit applications.
