NEOZED fuse link, D02, 20 A, gR, Un AC: 400 V, Un DC: 250 V, SILIZED SILIZED 5SE semiconductor protection fuses protect power semiconductors from the effects of a short circuit. The SILIZED fuse system from Siemens, as an important component of the SENTRON protection components for electrical installations, offers effective protection for people, equipment and systems by safely switching off in the event of an overload or short circuit. The area of application also includes frequency converters with fuses in the input and DC intermediate circuit as well as UPS systems and soft starters for motors. The Siemens SITOR fuses are characterized above all by: 1. Super-fast shutdown characteristics compared to conventional NH fuses. 2. Available in DIAZED and NEOZED designs. 3. Power semiconductors are also safely protected in the event of a short circuit. 4. The Siemens quality standard ensures very good characteristic curve accuracy.
