Semiconductor protection NH fuse
SITOR
SIEMENS Low-Voltage Power Distribution
SITOR fuses protect power semiconductors from the effects of a short circuit because the super-quick disconnect characteristic is far quicker than that of conventional LV HRC fuses. They protect expensive devices and system components such as converters with fuses in the input and in the DC link, UPS systems and soft starters for motors.
Panel mounting requirements have given rise to various connection versions and designs.
