Overview
Ferraz Shawmut’s British Standard UREJURSIURT Semiconductor Protection Fuses are designed to protect power semiconductors according to IEC 269.1 and 4, with a 660V voltage rating according to IEC 33 Class.
Key Features
These fuses offer an extremely high interrupting rating, making them suitable for a wide range of applications. They are available in various sizes, including 10 x 51, 17 x 49, and 2 x 17 x 49, with current ratings from 5 to 160A.
Compliance and Certifications
The fuses comply with BS 88-4, with and without indicators, and meet the requirements of VDE 636-23 and IEC 269.4 for aR and gR classes.
Operating Characteristics
The minimum operating voltage for all trip indicators is 20V. The fuses have been tested for their interrupting rating, with curves provided to indicate the pre-arcing time versus the RMS pre-arcing current.
