SIBA 2029221 Series

SIBA 2029221 is a very fast-acting, semiconductor protection fuse from the NH000 series, designed for high voltage applications with ratings of 700V or 690V. It is an "aR" (asymmetric-short-circuit) fuse, which can be used for both AC and DC circuits and is suitable for over-current and short-circuit protection in high voltage installations. These fuses feature knife blade contacts and can be fitted in an open fuse base, often coming with an optional integral blown fuse indicator or a trip indicator micro-switch.
