What are High-Speed Fuses?
High-speed fuses are thermal, current-controlled devices used for semiconductor electrical circuit
protection. Their element profile and body construction are specifically designed to
have the short-circuit characteristics necessary for protecting semiconductor devices: low
energy let-through (l2t), low peak currents (IPEAK), low-arc voltage and high heat dissipation. High-speed
fuses are the only type of circuit protection device that can protect them from overcurrent faults due to
their low energy let-through characteristics.
High-speed fuses consist of one or more current carrying elements that are enclosed within a chamber.
The chamber is fitted with contacts (also known as blade/end-bells or terminations) so that the fuse may
be readily inserted into and removed from an electrical circuit. Unlike general industrial fuses, high-speed
fuses do not have intentional time-delay features.
