Littelfuse L25S030 Semiconductor Fuse 30A 250VAC 250VDC Very Fast-Acting

Engineered for superior protection in demanding environments, the L25S Series from Littelfuse is an advanced semiconductor fuse designed to manage overcurrents with exceptional reliability. Capable of interrupting all overcurrents up to an impressive 200,000 amperes, this fuse not only meets current system demands but anticipates future needs as well. Its low I²t and peak let-through currents position it as an extremely current-limiting option, making it ideal for safeguarding sensitive semiconductor components. Recognized by Underwriters Laboratories, this fast-acting device is suitable for supplementary protection in UL listed equipment, ensuring peace of mind in your electrical systems.
