Many styles of innovative, versatile fuses are available to protect circuits from dangerous overcurrents in automotive, electronic, and industrial applications

Fuses are designed to allow electric currents to safely flow during normal operation but will quickly open when an overcurrent develops. They are crucial for protecting personnel and equipment if a short circuit or an overload condition arises.

Their defining characteristics include their physical size, electrical ratings, construction, opening speed and safety agency approvals. At OptiFuse, many styles of innovative, versatile fuses are available so you can choose the right fuse for your application.
