The SB aR Fuse-Link, rated for 450A and suitable for 690V AC according to IEC standards, offers significant adaptability for equipment design while ensuring optimal protection for power conversion systems. This particular fuse-link is designed with ultra-fast acting characteristics and is available in various sizes, each supporting multiple globally accepted mounting styles.

Engineered specifically for semiconductor components such as diodes, thyristors, and IGBT devices, the SB aR fuse-links utilize die-cut elements embedded in solidified sand, effectively controlling arcing behavior to achieve a reduced I²t value and a high interrupting capacity of 200 kA. Furthermore, the silver-plated contact surfaces and non-magnetic hardware enhance performance and reliability. A low voltage trip indicator can be integrated into each fuse-link, enabling operation of a field-mountable microswitch as needed.
